In an hour, Emily can type 60 words *60 minutes =

<<60*60=3600>>3600 words. It will take her 10800/3600 = <<10800/3600=3>>3 hours to write 10800 words. #### 3 Jasmine wants to organize her books in order of most number of pages to least number of pages. Jasmine's longest book has 396 pages and her shortest book has one-fourth as many pages as the longest. If the book in the middle of her shelf has three times the number of pages of the shortest book, then how many pages does the middle book have? Jasmine's shortest book is 1/4 * 396 pages = <<1/4*396=99>>99 pages long. The middle book is 3 * 99 pages = <<3*99=297>>297 pages long. #### 297 Hayden works for a limousine company as a driver. He gets reimbursed for any gas he puts in the limo, his hourly wage is $15, and he gets paid an additional $5 for every ride he gives. A positive review from a rider in his limo also gets him a $20 bonus. Today, he gave rides to three groups, drove for eight hours, and had to put 17 gallons of gas at $3 per gallon in the limo to refill the tank. He got two good reviews. How many dollars is he owed for his work today? Hayden gave 3 groups rides, so he is owed 3 * 5 = $<<3*5=15>>15. He drove for 8 hours, so he is owed 15 * 8 = $<<15*8=120>>120. He refilled the gas tank, so he is owed back 17 * 3 = $<<17*3=51>>51. He got two good reviews for a bonus of 2 * 20 = $<<2*20=40>>40. Hayden is owned 15 + 120 + 51 + 40 = $<<15+120+51+40=226>>226 for his work today. #### 226 Three years from now, Tully will be twice as old as Kate. How old was Tully a year ago if Kate is now 29 years old? Three years from now, Kate will be 29 years + 3 years = <<29+3=32>>32 years old. So by that time, Tully will be 32 years x 2 = <<32*2=64>>64 years old. This means, Tully is 64 years - 3 years = <<64-3=61>>61 years old now. Therefore, Tully was 61 years - 1 year = 60 years old last year. #### 60 Darcie is 4 years old. She is 1/6 as old as her mother and her mother is 4/5 as old as her father. How old is her father? Darcie's mother is 4*6=<<4*6=24>>24 years old. Darcie's father is 24/4*5=<<24/4*5=30>>30 years old. #### 30 Bertha plays tennis. Every ten games, one of her tennis balls wears out. Every five games, she loses a ball. Every four games, she buys a canister of three balls. She started with two balls and gave one to her partner. After twenty games, how many tennis balls does she have? Bertha wears out 20 / 10 = <<20/10=2>>2 tennis balls in 20 games. She loses 20 / 5 = <<20/5=4>>4 tennis balls in 20 games. She buys canisters of 3 * 20 / 4 = <<3*20/4=15>>15 tennis balls in 20 games. Bertha started with 2 balls and gave 1 away, so she has 2 + 15 - 2 - 4 - 1 = <<2+15-2-4-1=10>>10 tennis balls after twenty games. #### 10 Mark has a really bad headache. He takes 2 Tylenol tablets of 500 mg each and he does every 4 hours for 12 hours. How many grams of Tylenol does he end up taking? He takes 12/4=<<12/4=3>>3 doses Each dose is 500*2=<<500*2=1000>>1000 mg So he takes 3*1000=<<3*1000=3000>>3000 mg So he takes 3000/1000=<<3000/1000=3>>3 grams of Tylenol #### 3 Dave weighs 175 pounds and can bench press three times his body weight. Craig can only bench press 20% of the amount Dave can. Mark is new and can bench press 50 pounds less than Craig. How much can Mark bench press? Dave weighs 175 pounds and can bench press three times his body weight, so he can bench press 175*3 = <<175*3=525>>525 pounds Craig can only bench press 20% of Dave's 525 pounds, so Craig can bench press .20*525 = <<20*.01*525=105>>105 pounds Craig bench presses 105 pounds and Mark does 50 pounds less than Craig, so Mark can only press 105-50 = <<105-50=55>>55 pounds #### 55 Jon makes 3/4's the salary that Karen makes. John makes $3000 per month. How long will it take him to make the same amount of money that Karen does in 3 months? Karen makes $3000 / (3/4) = $<<3000/(3/4)=4000>>4000 per month. In three months, Karen would make a total of $4000 * 3 = $<<4000*3=12000>>12000. To make the same amount of money John would need to work $12000 / $3000 = <<12000/3000=4>>4 months. #### 4 Frank's laundry detergent is double concentrated and will wash 80 loads of laundry. His detergent is usually $25.00 a bottle but they're having a sale. If he buys 2 bottles, both bottles will drop to $20.00 a bottle. How much does he spend, in cents, per load of laundry, if he buys 2 bottles of detergent? If he buys 2 bottles, the price drops to $20.00 per bottle so they cost 2*20 = $<<2*20=40.00>>40.00 He can get 80 loads of laundry per bottle and he bought 2 bottles so that's 80*2 = <<80*2=160>>160 loads of laundry The detergent cost $40.00 and he will be able to wash 160 loads of laundry so each load costs 40/160 = $<<40/160=0.25>>0.25 #### 25
