Answer this question:Austin is a surfer. He took a trip to the beach during surfing season and the highest wave he caught was two feet higher than four times his height. The shortest wave he caught was four feet higher than his height. The shortest wave was three feet higher than his 7-foot surfboard is long. How tall was the highest wave Austin caught?
The shortest wave was 7 + 3 = 10 feet tall. Austin is 10 - 4 = 6 feet tall. Thus, the highest wave Austin caught was 6 * 4 + 2 = 24 + 2 = 26 feet tall.

Answer this question:Basil gets 1/2 of a dog cookie in the morning and before bed. She gets 2 whole cookies during the day. Basil's cookies are packaged with 45 cookies per box. How many boxes will she need to last her for 30 days?
Basil gets 1 / 2 in the morning and 1 / 2 at bedtime so she gets 1 / 2 + 1 / 2 = 1 whole cookie. Basil also gets 2 whole cookies during the day so all total she gets 2 + 1 = 3 whole cookies. She needs cookies for 30 days and eats 3 a day so she needs 30 * 3 = 90 cookies. Her cookies come 45 per box and she needs 90 cookies so she needs 90 / 45 = 2 boxes of cookies.
The answer is 2.

Answer this question:John repairs 5 cars. 3 of the cars take 40 minutes each to repair. The remaining ones take 50% longer each to repair. He makes $20 per hour repairing cars. How much money does he make?
The 3 cars take 3 * 40 = 120 minutes to make. He repairs 5 - 3 = 2 more cars. They each take 40 * .5 = 20 minutes longer per car. So they each take 40 + 20 = 60 minutes. So he repaired cars for 120 + 2 * 60 = 240 minutes. That is 240 / 60 = 4 hours. So he made 4 * 20 = $80.
The answer is 80.
