[Question]Janet lives in a city built on a grid system. She walks 3 blocks north, then seven times as many blocks west. Then she turns around and walks 8 blocks south and twice as many blocks east in the direction of her home. If Janet can walk 2 blocks/minute, how long will it take her to get home?
[Answer]First, find the total number of blocks south Janet is from her starting point by subtracting the blocks she walked north from the blocks she walked south: 8 blocks - 3 blocks = 5 blocks. Then find the number blocks she walked west: 3 blocks * 7 = 21 blocks. Then find the number of blocks she walked east: 8 blocks * 2 = 16 blocks. Subtract the number of blocks she walked east from the number of blocks she walked west to find how many blocks west of her starting point she is: 21 blocks - 16 blocks = 5 blocks. Add the number of blocks she needs to walk north to the number of blocks she needs to walk east: 5 blocks + 5 blocks = 10 blocks. Finally, divide the distance she needs to walk by her speed to find how long she'll spend walking: 10 blocks / 2 blocks / minute = 5 minutes. The answer is 5.
Q: Chelsea made 4 batches of cupcakes for the bake sale. The cupcakes took 20 minutes to bake and 30 minutes to ice per batch. How long did it take Chelsea to make the cupcakes?
A: Chelsea baked 4 batches of cupcakes x 20 minutes each = 80 minutes of baking. She iced 4 batches of cupcakes x 30 minutes each = 120 minutes. It took Chelsea 80 + 120 = 200 minutes to make the cupcakes for the bake sale. The answer is 200.
Question: Before James starts the strength phase training of his cycle he has a powerlifting total of 2200 pounds at a bodyweight of 245 pounds. He manages to gain 15% on his total and 8 pounds of body weight. What is the ratio of his lifting total to bodyweight?
Answer: He added 2200 * .15 = 330 pounds to his total. That means his new title is 2200 + 330 = 2530 pound total. His new body weight is 245 + 8 = 253 pounds. So he has 2530 / 253 = 10 for his ratio. The answer is 10.
[Question]Roberta wants to have a dinner party centered around soufflés. Each savory souffle calls for 8 eggs each and the dessert ones call for 6 eggs each. She wants to make 3 savory soufflés and 5 dessert soufflés for the party. How many eggs will she need?
[Answer]The savory soufflés need 8 eggs each and she wants to make 3 of these so she needs 8 * 3 = 24 eggs. The dessert soufflés need 6 eggs each and she wants to make 5 of these so she needs 6 * 5 = 30 eggs. For the dinner party she will need 24 + 30 = 54 eggs in total. The answer is 54.
Q: Carmen had 28 cats and 18 dogs before she gave 3 of the cats up for adoption. How many more cats than dogs does Carmen have now?

First find the total cost of the drink tickets: 5 tickets * $7 / ticket = $35. Then add that cost to the cost of the ticket to find the total cost: $35 + $181 = $216. Then multiply Jenna's hourly rate by the number of hours she works each week to find her weekly earnings: $18 / hour * 30 hours / week = $540 / week. Then multiply her weekly earnings by the number of weeks she works each month: $540 / week * 4 weeks / month = $2160 / month. Then divide the cost of the concert by Jenna's monthly earnings and multiply by 100% to express the answer as a percentage: $216 / $2160 * 100% = 10%. The answer is 10.
