Nikola is saving up for a bag of ant food before he can start his ant farm. He wants 400 ants in his farm. Each ant needs 2 ounces of food. Every ounce of ant food costs $.1. Nikola is saving up by raking leaves. He charges $5 to start a job and then he charges by the leaf. Each leaf he rakes costs 1 penny. He finally saved up enough money after he raked 6,000 leaves. How many jobs did he complete?

The ants will need 800 ounces of food because 400 x 2 =

<<400*2=800>>800 The ant food will cost $80 because 800 x .1 = <<800*.1=80>>80 He has earned $60 from the leaves he has raked because 6000 leaves * $0.01/leaf = $<<6000*0.01=60>>60 He earned $20 from all his jobs because 80 - 60 = <<80-60=20>>20 He completed 4 jobs because 20 / 5 = <<20/5=4>>4 #### 4 А Senior Center is hosting a bingo night. $2,400 in prize money will be given away. The first winner of the night will receive a third of the money. The next ten winners will each receive a 10th of the remaining amount. How many dollars will each of the next ten winners receive? The first winner will receive 2400 / 3 = $<<2400/3=800>>800. There will be 2400 - 800 = $<<2400-800=1600>>1600 left. The other winners will receive 1600 / 10 = $<<1600/10=160>>160 each. #### 160 Mark is filling a punch bowl that can hold 16 gallons of punch. He fills it part way, then his cousin comes along and drinks half the punch in the bowl. Mark starts to refill the bowl and adds 4 more gallons, but then his friend Sally comes in and drinks 2 more gallons of punch. After that, Mark has to add 12 gallons of punch to completely fill the bowl. How much punch did Mark initially add to the bowl? First, figure out how much punch was left in the bowl before Mark refilled it by subtracting the 12 gallons he added from the bowl's total capacity: 16 - 12 = <<16-12=4>>4 gallons Next, figure out how much punch was in the bowl before Sally came along: 4 + 2 = <<4+2=6>>6 gallons. Next, figure out how much punch was in the bowl before Mark started to refill it: 6 - 4 = <<6-4=2>>2 gallons Finally, multiply that amount by 2 to find out how much punch there was before the cousin drank half: 2 * 2 = <<4=4>>4 gallons #### 4 A sack of rice, which is 50 kilograms, costs $50. If David sells it for $1.20 per kilogram, how much will be his profit? David's revenue for the 50 kilograms of rice is $1.20 x 50 = $<<1.20*50=60>>60. So, his profit is $60 - $50 = $<<60-50=10>>10. #### 10 In the honey shop, the bulk price of honey is $5 per pound and the minimum spend is $40 before tax. The honey is taxed at $1 per pound. If Penny has paid $240 for honey, by how many pounds has Penny’s purchase exceed the minimum spend? Including tax, a pound of honey costs 5 + 1 = <<5+1=6>>6 dollars The minimum purchase equals 40 / 5 = <<40/5=8>>8 pounds of honey. Penny has bought 240 / 6 = <<240/6=40>>40 pounds of honey Penny has exceeded the minimum purchase by 40 - 8 = <<40-8=32>>32 pounds. #### 32 Lars owns a bakeshop. She can bake 10 loaves of bread within an hour and 30 baguettes every 2 hours. If she bakes 6 hours a day, how many breads does she makes? Lars can bake 10 x 6 = <<10*6=60>>60 loaves of bread every day. She can also bake 30 x 3 = <<30*3=90>>90 baguettes every day. Therefore the total bread she can bake is 60 + 90 = <<60+90=150>>150. #### 150 We harvested 405 kg of apples. 90 kg were used to make fruit juice and 60 kg were given to a restaurant. The rest was sold in 5 kg bags and their sale brought in $408. What was the selling price of one bag of apples? The weight of apples used for juice and given to the restaurant is 60 + 90 = <<60+90=150>>150 kg Thus 405 – 150 = 255kg worth of apples were sold in 5 kg bags. There were 255 / 5 = <<255/5=51>>51 bags sold. So each bag was sold for 408 / 51 = $<<408/51=8>>8 #### 8 In 5 years, Joey will be as old as Beth is now. If Joey is 9 now, how old was Joey when Beth was Joey's age now? Beth is 5+9=<<5+9=14>>14 now. Beth was 9 years old 14-9=<<14-9=5>>5 years ago. Joey was 9-5=<<9-5=4>>4. #### 4 Gerald had 20 toy cars. He donated 1/4 of his toy cars to an orphanage. How many toy cars does Gerald have left? Gerald gave away 20 x 1/4 = <<20*1/4=5>>5 of his toy cars. Therefore, he is left with 20 - 5 = <<20-5=15>>15 toy cars. #### 15 There are 28 students in a class. Two-sevenths of them were absent last Monday. How many students were present last Monday? 28 x 2/7 = <<28*2/7=8>>8 students were absent last Monday. So, 28 - 8 = <<28-8=20>>20 students were present last Monday. #### 20
