Freddy is 2 years younger than Stephanie. Stephanie is 4 times as old as Job. If Job is 5, how old is Freddy?

Stephanie is 5 * 4 =

<<5*4=20>>20 years old Freddy is 20 - 2 = <<20-2=18>>18 years old #### 18 Bo is learning words for the GRE. He got 800 flashcards. He knew 20% of the words on them. He has 40 days to learn the rest. How many words does he need to learn a day? He knows 800*.2=<<800*.2=160>>160 words So he needs to learn 800-160=<<800-160=640>>640 words That means he needs to learn 640/40=<<640/40=16>>16 words per day #### 16 Mike is 16 years old. His sister Barbara is half as old as he is. How old is Barbara going to be when Mike is 24 years old? Barbara is currently 16 years / 2 = <<16/2=8>>8 years old. Mike is going to be 24 years old after 24 years - 16 years = <<24-16=8>>8 years. So Barbara is going to be 8 years + 8 years = <<8+8=16>>16 years old. #### 16 Val has three times as many dimes as nickels. If she accidentally finds twice as many nickels as she has in her older brother's treasure box, and takes them for herself, what would be the value of money she has, in dollars, if she had 20 nickels before finding the new ones from her brother's treasure box? If Val currently has 20 nickels and finds twice as many nickels as she has in her older brother's treasure box, she will have 2*20=40 more nickels. The total number of nickels she'll have is 40+20=<<40+20=60>>60 Since nickel is worth $0.05, the value of the nickels Val is having is 60*0.05=$<<60*0.05=3>>3 Val had three times as many dimes as nickels before she found the 40 new nickels, a total of 3*20=<<3*20=60>>60 dimes Since a dime has a value of $0.10, the value of the dimes that Val has is 60*$0.10=$<<60*0.10=6>>6 Together, the value of the dimes and nickels Val has is worth $6+$3=$<<6+3=9>>9 #### 9 If Amanda can run the length of a football field 2000 meters in length in 2 hours, how long would it take her to run the length of a 10000-meter track at the same speed? Running the length of a football field 2000 meters in 2 hours is a speed of 2000/2=<<2000/2=1000>>1000 meters per hour. At the same speed, Amanda will run the length of a 10000-meter track in 10000/1000 = <<10000/1000=10>>10 hours #### 10 There were some snowflakes at first. It snowed an additional 4 snowflakes every 5 minutes. If there were 58 snowflakes after 1 hour, how many snowflakes were there at first? There are 60/5=<<60/5=12>>12 5-minute intervals in 1 hour. 12*4=<<12*4=48>>48 snowflakes fell in 1 hour. There were 58-48=<<58-48=10>>10 snowflakes at first. #### 10 Annie has 6 barrettes, twice as many scrunchies as barrettes, and three fewer bobby pins than barrettes. What percentage of her hair decorations are bobby pins, rounded to the nearest percent? First find the total number of scrunchies: 6 barrettes * 2 = <<6*2=12>>12 scrunchies Then subtract three fewer bobby pins than barrettes 6-3 =<<6-3=3>>3 bobby pins Then add the number of each type of hair decorations to find the total number: 6 decorations + 12 decorations + 3 decorations = <<6+12+3=21>>21 decorations Then divide the number of bobby pins by the total number of decorations and multiply by 100% to express the answer as a percentage: 3 bobby pins / 21 decorations * 100% = 14.28 which rounds down to 14% #### 14 Simeon drinks 64 fluid ounces of filtered water every day. He used to drink this water in 8-ounce-servings. But now, he drinks his water in 16-ounce servings. How many fewer servings per day does it now take Simeon to drink his water than it used to? In 64 fluid ounces, there are 64/8=<<64/8=8>>8 eight-ounce servings. Using 16-ounce servings, Simeon now drinks 64 ounces in 64/16=<<64/16=4>>4 servings. Thus, Simeon now drinks his water in 8-4=<<8-4=4>>4 fewer servings per day. #### 4 Lyra has an $80 budget for a week to spend on food. If she bought 1 bucket of fried chicken that costs $12 and 5 pounds of beef that cost $3 per pound. How much is left on her weekly budget? Five pounds of beef cost $3 x 5 = $<<3*5=15>>15. So Lyra spent a total of $12 + $15 = $<<12+15=27>>27. Therefore, $80 - $27 = $<<80-27=53>>53 is left on her weekly budget. #### 53 A bear is hunting for her cubs and herself. She needs 210 pounds of meat in a week. Each cub needs 35 pounds a week and she has 4 cubs. She hunts rabbits, which are five pounds each. If she hunts daily, how many rabbits does she need to catch each day? The cubs need 140 pounds a week because 4 x 35 = <<4*35=140>>140 The family needs 350 pounds a week because 210 + 140 = <<210+140=350>>350 The family needs 50 pounds a day because 350 / 7 = <<350/7=50>>50 She needs to hunt 10 rabbits a day because 50 / 5 = <<10=10>>10 #### 10
