Greta worked 40 hours and was paid $12 per hour. Her friend Lisa earned $15 per hour at her job. How many hours would Lisa have to work to equal Greta's earnings for 40 hours?

For the 40 hours worked, Greta earned a total of 40 * 12 = $

<<40*12=480>>480. To find how many hours Lisa has to work to earn $480, we divide 480 / 15 = <<480/15=32>>32 #### 32 Elroy decides to enter a walk-a-thon and wants to make sure he ties last year's winner's cash collection. Last year, walkers earned $4 a mile. This year walkers earn $2.75 a mile. If last year's winner collected $44, how many more miles will Elroy walk than last year's winner to collect the same amount of money? Last year's winner walked 11 miles because 44 / 4 = <<44/4=11>>11 Elroy has to walk 16 miles to collect $44 because 44 / 2.75 = <<44/2.75=16>>16 Elroy will walk 5 more miles because 16 - 11 = <<16-11=5>>5 #### 5 Cindy has 37 envelopes. If Cindy gives 3 envelopes to each of her 5 friends, how many envelopes does she have left? Cindy gave 3 envelopes/friend x 5 friends = <<3*5=15>>15 envelopes to her friends. Cindy has 37 envelopes - 15 envelopes = <<37-15=22>>22 envelopes left. #### 22 The dog toys Samantha buys for her dog are "buy one get one half off" and all cost $12.00 each. She buys 4 toys. How much does she spend on dog toys? If she buys 1 toy at $12.00 she gets the 2nd toy 1/2 off, the 2nd toy is 12*.5 = $<<12*.5=6.00>>6.00 1 full-priced toy is $12.00 and 1/2 priced toy is $6.00 so these 2 toys come to 12+6 = $<<12+6=18.00>>18.00 She buys 2 more toys that are "buy one get one 1/2 off" so all total she spends 2*18 = $<<2*18=36.00>>36.00 #### 36 Todd borrowed $100 from his brother to start a snow-cone stand. He has to repay him $110 as soon as he can. Todd spent $75 on ingredients for the snow cones. He sells 200 of them for $.75 each. After he pays back his brother, how much money does Todd have? Todd has $25 left after buying ingredients because 100 - 75 = <<100-75=25>>25 Todd made $150 selling snow-cones because 200 x .75 = <<200*.75=150>>150 Todd has $175 before he pays his brother back because 25 + 150 = <<25+150=175>>175 After Todd pays his brother back he has $65 because 175 - 110 = <<175-110=65>>65 #### 65 Ariana heard the news that a new grocery store had opened up in their town, so she decided to buy some flowers for her house. She bought a bunch of 40 flowers, 2/5 of which were roses, 10 were tulips, and the rest were carnations. How many carnations did she buy? The number of roses in the bunch is 2/5 * 40 flowers = <<2/5*40=16>>16 flowers The total number of roses and tulips is 16 flowers + 10 flowers = <<16+10=26>>26 flowers There were 40 flowers - 26 flowers = <<40-26=14>>14 carnations #### 14 Bob is building a vegetable garden. It is 220 feet long by 120 feet wide. Half of the garden is going to be tilled land. A third of the rest of it will have trellises for vining plants, and the rest will be devoted to raised beds. How big will the raised bed section of the garden be? The garden is 220 * 120 = <<220*120=26400>>26,400 square feet. The tilled land will take up half the area, and the trellises and raised beds will be the other half. Each half is 26,400 / 2 = <<26400/2=13200>>13,200 square feet. The trellises will take up 1/3 of the remaining land, so the raised beds will take 1 - 1/3 = 2/3 of the remaining land. So the total area of the raised bed area will be 13,200 square feet * (2 / 3) = <<13200*(2/3)=8800>>8,800 square feet. #### 8800 At a coffee shop, 7 customers order coffee at $5 each and 8 customers order tea at $4 each. How much money did the coffee shop make? Sale from coffee is 7 x $5 = $<<7*5=35>>35. Sale from tea is 8 x $4 = $<<8*4=32>>32. Total sales is $35 + $32 = $<<35+32=67>>67. #### 67 Lex is picking apples in his apple orchard when he notices some of the apples have bruises and some have worms. He wants to save the bruised apples to make applesauce, throw the wormy apples away, and keep the unbruised apples to eat raw. By his count, a fifth of the apples have worms and nine more than one fifth are bruised. He picked 85 apples. How many apples will he have left to eat raw? A fifth of the apples have worms, so Lex has to throw 85 / 5 = <<85/5=17>>17 apples away. Nine more have bruises than worms, so Lex has 17 + 9 = <<17+9=26>>26 apples for applesauce. He picked 85 apples, so Lex has 85 - 26 - 17 = <<85-26-17=42>>42 apples left to eat raw. #### 42 Trent walked 4 blocks from his house to the bus stop. He rode the bus 7 blocks to the library. Later, he came home the same way. How many blocks did Trent travel in all? On the way to the library, Trent went 4 blocks + 7 blocks = <<4+7=11>>11 blocks. Trent came home the same way so he went 11 blocks + 11 blocks = <<11+11=22>>22 blocks. #### 22
