A play was held in an auditorium and its ticket costs $10. An auditorium has 20 rows and each row has 10 seats. If only 3/4 of the seats were sold, how much was earned from the play?
Let's think: There are 20 x 10 = 200 seats in the auditorium. Only 200 x 3 / 4 = 150 seats were sold. Hence, the earnings from the play is $10 x 150 = $1500.. The answer is: 1500.

Katy participated in a summer reading program at her local library. She read 8 books in June, twice as many in July and three fewer in August than she did in July. How many books did Katy read during the summer?
Let's think: Katy read twice as many books in July as she did in June, so she read 2 * 8 = 16 books in July. She read three fewer books in August than she did in July, so she read 16 - 3 = 13 books in August. So, including June, she read 8 + 16 + 13 = 37 books total.. The answer is: 37.

Tabitha adds 1 serving of honey per cup of tea in the evening. She usually has 2 cups of tea before bed. She buys her honey in a 16-ounce container. If there are 6 servings of honey per ounce, how many nights will she be able to enjoy honey in her tea before bed?
Let's think: She has 1 serving of honey per cup of tea and she has 2 teas at night so she needs a total of 1 * 2 = 2 servings per night. There are 6 servings in 1 ounce and she has a 16 - ounce jar of honey so that's 6 * 16 = 96 servings of honey. Her jar has 96 servings and she has 2 servings a night so 1 jar will last her 96 / 2 = 48 nights.. The answer is: 48.

Mark hires a singer for 3 hours at $15 an hour. He then tips the singer 20%. How much did he pay?
Let's think:
The cost was 15 * 3 = $45. So the tip was 45 * .2 = $9. So in total, he paid 45 + 9 = $54.. The answer is: 54.
