Gerald spends $100 a month on baseball supplies. His season is 4 months long. He wants to use the months he's not playing baseball to save up by raking, shoveling, and mowing lawns. He charges $10 for each. How many chores does he need to average a month to save up for his supplies?

He needs to save up $400 because 4 x 100 =

<<4*100=400>>400 He has 8 months to earn this money because 12 - 4 = <<12-4=8>>8 He needs to earn $50 a month because 400 / 8 = <<400/8=50>>50 He needs to do 5 tasks a month because 50 / 10 = <<50/10=5>>5 #### 5 Ann is cutting fabric to make curtains. She cuts a 4 foot by 6 foot rectangle for the living room, and a 2 foot by 4 foot rectangle for the bedroom. If the bolt of fabric is 16 feet by 12 feet, how much fabric is left in square feet? First figure out how many square feet the original bolt of fabric was: 16 feet * 12 feet = <<16*12=192>>192 square feet Then figure out how much fabric Ann took for the living room curtains: 4 feet * 6 feet = <<4*6=24>>24 square feet Then figure out how much fabric Ann took for the bathroom curtains: 2 feet * 4 feet = <<2*4=8>>8 square feet Finally, subtract the square footage of both sets of curtains from the total square footage: 192 - 24 - 8 = <<192-24-8=160>>160 square feet #### 160 Arnel had ten boxes of pencils with the same number of pencils in each box. He kept ten pencils and shared the remaining pencils equally with his five friends. If his friends got eight pencils each, how many pencils are in each box? Arnel shared 5 x 8 = <<5*8=40>>40 pencils with his friends. So, he had 10 + 40 = <<10+40=50>>50 pencils in all. Therefore, each box had 50/10 = <<50/10=5>>5 pencils inside. #### 5 Caleb bought 10 cartons of ice cream and 4 cartons of frozen yoghurt. Each carton of ice cream cost $4 and each carton of frozen yoghurt cost $1. How much more did Caleb spend on ice cream than on frozen yoghurt? The cost of the ice cream is 10 × $4 = $<<10*4=40>>40. The cost of the frozen yoghurt is 4 × $1 = $<<4*1=4>>4. Caleb spent $40 − $4 = $36 more on ice cream than on frozen yogurt. #### 36 Leah earned $28 working odd jobs around the neighborhood. She spent a seventh of it on a milkshake and put half of the rest in her savings account. She left the remaining money in her wallet. Her dog got ahold of her wallet and shredded all the money inside but $1. How many dollars did Leah lose? Leah spent 28 / 7 = $<<28/7=4>>4 on a milkshake. She had 28 - 4 = $<<28-4=24>>24 left. She put half in her savings account and half in her wallet, so she had 24 / 2 = $<<24/2=12>>12 in her wallet. Her dog shredded all the money in her wallet but $1, so Leah lost 12 - 1 = $<<12-1=11>>11. #### 11 There are 25 roses in a garden. There are 40 tulips. There are 35 daisies. What percentage of flowers are not roses? There are 25+40+35=<<25+40+35=100>>100 flowers total. There are 40+35=<<40+35=75>>75 flowers that are not roses. Therefore, (75/100)*100=<<(75/100)*100=75>>75% of the flowers are not roses. #### 75 Leo's assignment was divided into three parts. He finished the first part of his assignment in 25 minutes. It took him twice as long to finish the second part. If he was able to finish his assignment in 2 hours, how many minutes did Leo finish the third part of the assignment? It took Leo 25 x 2 = <<25*2=50>>50 minutes to finish the second part of the assignment. Leo finished the first and second parts of the assignment in 25 + 50 = <<25+50=75>>75 minutes. He finished the entire assignment in 60 x 2 = <<60*2=120>>120 minutes. Therefore, it took Leo 120 - 75 = <<120-75=45>>45 minutes to finish the third part of the assignment. #### 45 Liza bought 10 kilograms of butter to make cookies. She used one-half of it for chocolate chip cookies, one-fifth of it for peanut butter cookies, and one-third of the remaining butter for sugar cookies. How many kilograms of butter are left after making those three kinds of cookies? Liza used 10/2 = <<10/2=5>>5 kilograms of butter for the chocolate chip cookies. Then, she used 10/5 = <<10/5=2>>2 kilograms of butter for the peanut butter cookies. She used 5 + 2 = <<5+2=7>>7 kilograms of butter for the chocolate and peanut butter cookies. So, only 10 -7 = <<10-7=3>>3 kilograms of butter was left. Then, Liza used 3/3 = <<3/3=1>>1 kilograms of butter for the sugar cookies. Therefore, only 3-1 = <<3-1=2>>2 kilograms of butter were left. #### 2 A Statistics student wants to find out the average daily allowance of the middle school students. According to his survey, 2/3 of the students receive an average of $6 allowance per day while the rest gets an average of $4 a day. If he surveyed 60 students, what is the total amount of money those 60 students get in a day? There are 60 students x 2/3 = <<60*2/3=40>>40 students who have a $6 daily allowance. While there are 60 students - 40 students = <<60-40=20>>20 students who have a $4 daily allowance. The sum of the allowances of the 40 students who received $6 daily is 40 students x $6/day = $<<40*6=240>>240. The sum of the allowances of the 20 students who received $4 daily is 20 students x $4/day = $<<20*4=80>>80. The total daily amount of money of those 60 students is $240 + $80 = $<<240+80=320>>320. #### 320 Every hour Joanne has to collect the coins out of the fountain inside the mall. During the first hour, she collected 15 coins. For the next two hours, she collected 35 coins from the fountain. In the fourth hour, she collected 50 coins from the fountain but she gave 15 of them to her coworker so she could buy a soda. How many coins did she have after the fourth hour? 15 coins collected in hour one 35 coins collected in hour two 35 coins collected in hour three 50 coins collected in hour four Before giving her coworker some coins there were 15+35+35+50=<<15+35+35+50=135>>135 coins The number of coins after given 15 to her coworker is 135-15=<<135-15=120>>120 #### 120
