Bella is making bracelets for her 6 friends. She needs 8 beads per bracelet. She has 36 beads. How many more beads does she need to make all six bracelets?

How many beads does Bella need to make all six bracelets? ** Bella needs a total of 8 beads x 6 friends =

<<8*6=48>>48 beads. How many more beads does Bella need to make all six bracelets? ** She needs 48 beads – 36 beads = <<48-36=12>>12 more beads. #### 12 Arthur has $200 in his wallet. He spends four-fifths of that. How much does he have left? How much did Arthur spend? ** Arthur spent 4/5 * $200 = $<<4/5*200=160>>160. How much does Arthur have left? ** Thus he has $200 - $160 = $<<200-160=40>>40 remaining. #### 40 Jonas is a book collector. He has so many books he is converting his third bedroom into a library. This room has 400 square feet of space. He plans to put several bookshelves in the room and each bookshelf takes up 80 square feet of space. If he reserves 160 square feet of space to use for a desk and some walking space, how many shelves can he put in the room? How many square feet of space is left? ** If he reserves 160 sq. ft. of space for a desk and some walking space, then he will have 400-160=<<400-160=240>>240 sq. ft. of space remaining. How many bookshelves can he put in the room? ** If each bookshelf takes up 80 sq. ft. of space, then 240 sq ft can contain 240/80=<<240/80=3>>3 bookshelves. #### 3 Once a week, it takes Kitty 5 minutes to pick up toys and straighten the living room. It takes another 20 minutes to vacuum the living room floor, seating and drapes. She spends 15 minutes cleaning the windows and 10 minutes dusting the furniture. After 4 weeks, how long has Kitty spent cleaning just the living room? How many minutes does Kitty spend cleaning the living room? ** 5 minutes for picking up toys, 20 minutes to vacuum, 15 minutes on windows and 10 minutes on furniture is 5+20+15+10 = <<5+20+15+10=50>>50 minutes How many minutes has Kitty spent cleaning the living room? ** After 4 weeks, she has spent 4 weeks * 50 minutes/week = <<4*50=200>>200 minutes cleaning the living room #### 200 Twice Betty's age is the cost of a pack of nuts. Doug, Betty's friend, is 40 years old. If the sum of their ages is 90, and Betty wants to buy 20 packs of the nuts, calculate the amount of money she'll pay for the packs of nuts. How old is Betty? ** If Doug, Betty's friend, is 40 years old, and the sum of their ages is 90, Betty is 90-40 = <<90-40=50>>50 years old. How much does a pack of nuts cost? ** Since twice Betty's age is the cost of a pack of nuts, a pack of nuts is sold at 2*$50 = $<<2*50=100>>100 How much money will Betty pay for the packs of nuts? ** If Betty wants to buy 20 packs of the nuts, she'll have to pay 20*$100 = $<<20*100=2000>>2000 #### 2000 A man is trying to maximize the amount of money he saves each month. In particular, he is trying to decide between two different apartments. The first apartment costs $800 per month in rent and will cost an additional $260 per month in utilities. The second apartment costs $900 per month and will cost an additional $200 per month in utilities. The first apartment is slightly further from the man's work, and the man would have to drive 31 miles per day to get to work. The second apartment is closer, and the man would only have to drive 21 miles to get to work. According to the IRS, each mile a person drives has an average cost of 58 cents. If the man must drive to work 20 days each month, what is the difference between the total monthly costs of these two apartments after factoring in utility and driving-related costs (to the nearest whole dollar)? How much will the first apartment cost in mileage? ** The mileage cost for the first apartment will be 31*20*0.58 = $<<31*20*0.58=359.60>>359.60 How much will the first apartment cost in total? ** This makes the total monthly cost of the first apartment 359.60 + 800 + 260 = $<<359.60+800+260=1419.60>>1419.60 How much will the second apartment cost in mileage? ** Similarly, the mileage cost for the second apartment will be 21*20*0.58 = $<<21*20*0.58=243.60>>243.60 How much will the second apartment cost in total? ** Thus, the total monthly cost of the second apartment is 243.60 + 900 + 200 = <<243.60+900+200=1343.60>>1343.60 What is the difference in total monthly costs? ** Therefore, the difference in total monthly costs is 1419.60 - 1343.60 = $<<1419.60-1343.60=76>>76 #### 76 Josh has some money. He spent $1.75 on a drink, and then spent another $1.25. If he had $6 left, how much money, in dollars, did Josh have at first? How much money did Josh spend? ** Josh spent 1.75+1.25=<<1.75+1.25=3>>3 dollars in total. How much money, in dollars, did Josh have at first? ** Josh had 6+3=<<6+3=9>>9 dollars at first. #### 9 Today, at the school science lesson, Jake learned that there are 8 more solar systems for every planet in the galaxy. If there are 20 planets in the galaxy, how many solar systems and planets are there altogether? How many solar systems are there? ** If there are 8 more solar systems for every planet in the galaxy, there are 8+1 = <<8+1=9>>9 solar systems for every planet. How many solar systems are there? ** Since the number of planets is 20, there are 20*9 = <<20*9=180>>180 solar systems in the galaxy. How many solar systems and planets are there altogether? ** Altogether, there are 180+20 = <<180+20=200>>200 solar systems and planets in the galaxy. #### 200 In a graveyard, there are 20 skeletons. Half of these skeletons are adult women, and the remaining number are split evenly between adult men and children. If an adult woman has 20 bones in their body, and a male has 5 more than this, and a child has half as many as an adult woman, how many bones are in the graveyard? How many adult women are there? ** We first need to figure out how many of each type of skeleton there are. Since half the 20 skeletons are adult women, that means there are 20/2=<<20/2=10>>10 adult women's skeletons. How many adult men and children are there? ** The remaining half, 10, is split between adult men and children, meaning there are 10/2= <<10/2=5>>5 of each. How many bones are in the 10 adult women's skeletons? ** Since an adult woman has 20 bones in their body, this means that the 10 skeletons have 20*10=<<20*10=200>>200 bones in total. How many bones does an adult man have? ** Since an adult man has 5 more bones in their body than an adult woman, this means they have 20+5= <<20+5=25>>25 bones in their body. How many bones are in the 5 adult men's skeletons? ** There are 5 adult men, meaning there are 25*5=<<25*5=125>>125 bones in the adult male skeletons in total. How many bones does a child have? ** Since a child has half as many bones as the 20 in an adult woman, this means the children have 20/2= <<20/2=10>>10 bones in their body. How many bones are in the 5 children's skeletons? ** Since there are 5 children, this means there are 5*10= <<5*10=50>>50 bones in the children's skeletons in total. How many bones are in the graveyard? ** Therefore, altogether there are 50+125+200= <<50+125+200=375>>375 bones in total in the graveyard. #### 375 When Spencer jumps rope, he jumps 4 times per minute. He jumps for 10 minutes each session and does 2 sessions each day. How many jumps will Spencer do in 5 days? How many times does Spencer jump in 1 session? ** In 1 session he jumps 4 times/minute * 10 minutes = <<4*10=40>>40 times How many sessions does Spencer do in 5 days? ** In 5 days he does 2 sessions/day * 5 days = <<2*5=10>>10 sessions How many times does Spencer jump in 5 days? ** He jumps 10 sessions * 40 times/session = <<10*40=400>>400 times in 5 days. #### 400
