[Question]: A swarm of ants discovered a pile of sugar that spilled from a dropped bag. They begin to harvest it and carry it off to their anthill. Every hour, the ants remove 4 ounces of sugar. The bag of sugar held 24 ounces before it was dropped. After three hours, how many more hours will the ants need to harvest the remaining sugar?
[Answer]: After 3 hours, the ants have removed 4 * 3 = 12 ounces of sugar. There are 24 - 12 = 12 ounces of sugar left. Thus, the ants need 12 / 4 = 3 more hours to harvest the remaining sugar.
So the answer is 3.

[Question]: The ratio of boys to girls at the dance was 3:4. There were 60 girls at the dance. The teachers were 20% of the number of boys. How many people were at the dance?
[Answer]: 60 girls represent 4 parts, so one part of students is 60 / 4 = 15 students. There are 15 * 3 = 45 boys at the dance. The teachers at the dance are 45 * 0,2 = 9 teachers at the dance. There are 60 + 45 + 9 = 114 people at the dance.
So the answer is 114.

[Question]: A pie shop charges $3 per slice of custard pie. They cut each whole pie into 10 slices. If they make 6 whole custard pies, how much money will the pie shop earn?
