The gauge on a water tank shows that the tank is 1/3 full of water. To fill the tank, 16 gallons of water are added. How many gallons of water does the tank hold when full?

Given that the tank is 1/3 full of water, and that it requires 16 gallons to fill. 1 full tank -1/3 tank = 2/3 of the tank is empty, which is equal to 16 gallons.

If 2/3 of the tank equals 16 gallons, this means 1/3 of the tank is equal to 16 / 2 gallons = 8 gallons

The total capacity of the tank or how much the tanks holds = 16 + 8 =

<<16+8=24>>24 gallons #### 24 In a car dealership, Fiona worked for 40 hours a week, John for 30 hours, and Jeremy for 25 hours. If the employees are paid $20 per hour, how much money does their boss spend paying all of them every month? Fiona earns 40 hours/week * $20/hour = $<<40*20=800>>800/week So she earns $800/week * 4 weeks/month = $3200/month John earns 30 hours/week * $20/hour = $<<30*20=600>>600/week So he earns $600/week * 4 weeks/month = $<<600*4=2400>>2400/month Jeremy earns 25 hours * $20/hour = $<<25*20=500>>500/week So he earns $500/week * 4 weeks/month = $2000/month Overall their boss has to spend $3200/month + $2400/month + $2000/month = $<<3200+2400+2000=7600>>7600/month #### 7600 Jeanine bought 18 pencils and Clare bought half as many pencils. If Jeanine gave one third of his pencils to Abby, how many more pencils than Clare does Jeanine have now? Clare bought half of 18 pencils which is 18/2 = <<18/2=9>>9 pencils One-third of 18 pencils is (1/3)*18 = <<18*1/3=6>>6 pencils Jeanine gave out 6 pencils so he has 18-6 = <<18-6=12>>12 pencils left Jeanine now has 12-9 = <<12-9=3>>3 pencils #### 3 Mark is a lawyer who works at the county courthouse every day. It takes him 5 minutes to find parking and 3 minutes to walk into the courthouse. 2 days of the week it takes him 30 minutes to get through the metal detector and the other 3 days are less crowded so he gets through in 10 minutes. How long does he spend on all these activities in a week with 5 work days? First find how long Mark spends on parking and walking each day: 5 minutes + 3 minutes = <<5+3=8>>8 minutes Then multiply that number by his number of workdays to find the total walking and parking time: 8 minutes/day * 5 days/week = <<8*5=40>>40 minutes/week Then multiply the number of long-wait days by the time of each long wait: 2 days/week * 30 minutes/day = <<2*30=60>>60 minutes/week Then multiply the number of short-wait days by the time of each short wait: 3 days/week * 10 minutes/day = <<3*10=30>>30 minutes/week Then add the length of time Mark spends on each activity to find the total time spent: 30 minutes/week + 60 minutes/week + 40 minutes/week = <<30+60+40=130>>130 minutes/week #### 130 A truck driver’s heavy semi truck can go 3 miles per gallon of gas. The truck driver needs to put gas in his truck at one gas station, but wants to put the minimum amount he needs to get him to a much cheaper gas station 90 miles away. He already has 12 gallons of gas in his tank. How many more gallons does the truck driver need to put in his semi to make it to the cheaper gas station? The truck driver can go 3 * 12 = <<3*12=36>>36 miles on the gas in his tank. He needs to go 90 - 36 = <<90-36=54>>54 more miles. Thus, the truck driver needs to put 54 / 3 = <<54/3=18>>18 more gallons of gas in his semi. #### 18 At Ken's local store, a pound of steak is going for $7. He decides to get two pounds. At the till, he pays using a $20 bill. How much money will he get back? 2 pounds of steak will cost Ken 2 * 7 = <<2*7=14>>14 dollars Subtracting that amount from $20 will give 20 - 14 = <<20-14=6>>6 dollars Ken will therefore get 6 dollars back. #### 6 Erin runs her own launderette and needs to cash in the change from the machines. There are 80 quarters and 100 dimes in every machine in the launderette. When Erin empties all of the machines and cashes in the change, she has a total of $90. She had no money before she emptied the machines and each machine held the same amount of money. How many machines are in the launderette? There are 4 quarters in a dollar so in quarters, each machine holds 80 quarters / 4 = $<<80/4=20>>20. There are 10 dimes in a dollar so in dimes, each machine holds 100 dimes / 10 = $10. Each machine therefore holds $20 in quarters + $10 in dimes = $<<20+10=30>>30. So Erin must therefore have $90 total income / $30 income per machine = <<90/30=3>>3 machines. #### 3 When Jeffrey walks, for every three steps forward, he takes two steps backwards. Therefore, if the distance between the house and the mailbox is 66 steps, what is the total number of steps Jeffrey takes when he goes from the house to the mailbox? For every 3 steps forward, he adds 2 more backwards so each 'step' gained costs 5 actual steps 66 steps distance * 5 steps moved = <<66*5=330>>330 steps total #### 330 Edmund is buying a new computer and needs to save up $75 before he has enough. He convinces his parents to pay him for extra chores. He normally has to do 12 chores a week. His parents agree to pay him $2 for every extra chore he does during the week. If he does 4 chores a day for two weeks, how much does he earn? In two weeks, he has to do 24 chores because 2 x 12 = <<2*12=24>>24 He now does 28 chores a week because 7 x 4 = <<7*4=28>>28 He does 56 chores in two weeks because 2 x 28 = <<2*28=56>>56 He has done 32 extra chores because 56 - 24 = <<56-24=32>>32 He earns $64 because 2 x 32 = <<2*32=64>>64 #### 64 Mrs. Amaro has 80 roses in her garden. Three-fourths of her roses are red, one-fourth of the remaining are yellow, and the rest are white. How many of Mrs. Amaro's roses are either red or white? Mrs. Amaro has 80 x 3/4 = <<80*3/4=60>>60 red roses. So, 80 - 60 = <<80-60=20>>20 roses are not red. Then, 20 x 1/4 = 5 of those 20 non-red roses are yellow. Hence, 20 - 5 = <<20-5=15>>15 roses are white. Therefore, 60 + 15 = <<60+15=75>>75 roses are either red or white. #### 75
