[Question]: An archer needs to practice. He intends to shoot 200 shots 4 days a week. He is able to recover 20% of his arrows. The arrows he uses cost $5.5 per arrow. His team agrees to pay for 70% of the cost of his arrows. How much does he spend for arrows a week?
[Answer]: He shoots 200 * 4 = 800 shots per week. He can recover 800 * .2 = 160 of those arrows. So he uses 800 - 160 = 640 arrows a week. The cost for those arrows would come out to 640 * 5.5 = $3520 per week. His team pays for 3520 * .7 = $2464 of that. So he has to pay 3520 - 2464 = $1056 per week for arrows.
So the answer is 1056.

[Question]: Michael was watching a TV show, which was aired for 1.5 hours. During this time, there were 3 commercials, which lasted 10 minutes each. How long (in hours) was the TV show itself, not counting commercials?
[Answer]: Each commercial lasted 10 minutes, so three commercials lasted 3 * 10 = 30 minutes. The show was aired for 1.5 hours, and 30 minutes is 0.5 of an hour, so without the commercials, the show was 1.5 - 0.5 = 1 hour long.
So the answer is 1.

[Question]: Jessica has a basic cable television service for $15 per month. If she adds the movie channels, it will cost an additional $12 per month. The sports channels cost $3 less per month than the movie channels. If Jessica adds the movie channels and the sports channels, what will her total monthly payment be?
[Answer]:
The sports channels cost $12 - $3 = $9 per month. Jessica has to pay $15 + $12 + $9 = $36 in total per month.
So the answer is 36.
