[Question]Jose owns a swimming pool. He charges $3 for kids and twice that amount for adults. If 8 kids and 10 adults swim in his swimming pool per day, how much money will he earn per week?
[Answer]Jose can earn $3 x 8 = $24 per day for kids. He charges $3 x 2 = $6 per adult. So, he can earn $6 x 10 = $60 per day for adults. Jose earns $60 + $24 = $84 per day for kids and adults. Therefore, he can earn $84 x 7 = $588 per week. The answer is 588.

[Question]Aaron and his brother Carson each saved up $40 to go to dinner. The bill is 3/4 of their total money. After, they go out for ice cream. Each scoop costs $1.5 and they get the same amount as each other. If they leave with $1 in change each, how many scoops did they each buy?
[Answer]They had $80 saved up because 2 x 40 = 80. They spent $60 because 80 x (3 / 4) = 60. They had $20 left for ice cream because 80 - 60 = 20. They had $2 left after leaving the ice cream shop because 2 x 1 = 2. They spent $18 on ice cream because 20 - 2 = 18. The bought 12 scoops of ice cream because 18 / 1.5 = 12. The each bought 6 scoops because 12 / 2 = 6. The answer is 6.

[Question]James buys 2 puzzles that are 2000 pieces each. He anticipates for these larger puzzles he can do 100 pieces every 10 minutes. So how long would it take to finish both puzzles?
[Answer]
His speed means he can do 10 / 100 = .1 minute per piece. So he can finish 1 puzzle in 2000 * .1 = 200 minutes. So these two puzzles take 200 * 2 = 400 minutes. The answer is 400.
