[Question]Chris’s internet bill is $45 per month for 100 GB and $0.25 for every 1 GB over. His bill for this month is $65. How many GB over was Chris charged for on this bill?
[Answer]Let G stand for the number of GB billed, so the total bill is $0.25G + $45 flat rate charge = $65 total bill. Now we will solve for G. $0.25G + $45 flat rate - $45 = $65 - $45. This simplifies to $0.25G = $20. $0.25G / $0.25 = $20 / $0.25. G = 80 GB were charged on this bill. The answer is 80.
Q: Randy walks his dog twice a day. After each walk, he wipes his dog's paws off with a baby wipe. The baby wipes come 120 wipes per pack. How many packs will he need to make sure he has enough wipes for 360 days?
A: He uses 2 wipes a day and the pack of baby wipes come 120 wipes per pack so they will last 120 / 2 = 60 days. He needs enough to last for 360 days and 1 pack will last 60 days so he needs 360 / 60 = 6 packs. The answer is 6.
Question: 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?
Answer: Bertha wears out 20 / 10 = 2 tennis balls in 20 games. She loses 20 / 5 = 4 tennis balls in 20 games. She buys canisters of 3 * 20 / 4 = 15 tennis balls in 20 games. Bertha started with 2 balls and gave 1 away, so she has 2 + 15 - 2 - 4 - 1 = 10 tennis balls after twenty games. The answer is 10.
[Question]James burned his hand in a freak accident. It takes him 4 weeks to heal enough to get a skin graft. After that it takes him 50% longer than that to heal from the skin graft. How long did he take to recover from everything?
[Answer]The skin graft took 4 * .5 = 2 weeks longer to recover from than the previous. So that means it took 4 + 2 = 6 weeks to recover from it. That means he took 4 + 6 = 10 weeks to recover from everything. The answer is 10.
