[Question]: James has a rainwater collection barrel. For each inch of rain he collects 15 gallons. On Monday it rained 4 inches and on Tuesday it rained 3 inches. He can sell water for $1.2 per gallon. How much money did he make from selling all the water?
[Answer]: It rained 3 + 4 = 7 inches. So he collected 7 * 15 = 105 gallons. So he makes 105 * 1.2 = $126 from selling the water.
So the answer is 126.

[Question]: Jennifer is building tanks to hold her goldfish. She built 3 tanks that will hold 15 fish each, heated, and filled them. She plans to build the rest of the tanks equipped with heaters, and they will hold 10 fish each. If she needs to build enough tanks to house a total of 75 fish, how many more will she need to build?
[Answer]: With the tanks already built it has room for 3 tanks * 15 fish / tank = 45 fish. The total of fish that still lack space is 75 fish - 45 fish = 30 fish. This means Jennifer needs 30 fish / 10 fish / tank = 3 tanks of 10 fish.
So the answer is 3.

[Question]: Skyler is a composer. He wrote 25 hit songs that made it on the top 10 charts; ten more songs that made it on the top 100 charts than the hit songs; 5 fewer songs than the hit songs that were never released. How many songs did Skyler write in all?
[Answer]:
Skyler wrote 25 + 10 = 35 songs that made it on the top 100. He wrote 25 - 5 = 20 songs that were never released. So, Skyler wrote a total of 25 + 35 + 20 = 80 songs.
So the answer is 80.
