Q: Two apartment roommates split the rent, utilities, and grocery payments equally each month. The rent for the whole apartment is $1100 and utilities are $114. If one roommate pays $757 in all, how many dollars are groceries for the whole apartment?
A: 300
Step-by-step reasoning process: Rent plus utilities for the whole apartment is 1100 + 114 = $1214. If one roommate pays $757 in all, the total cost of everything is 757 * 2 = 1514. The groceries cost 1514 - 1214 = 300.


Q: Charlie owns one flute, two horns, and a harp. Carli owns twice as many flutes as Charlie, half as many horns as Charlie, but no harps. What is the combined total number of musical instruments owned by Charlie and Carli?
A: 7
Step-by-step reasoning process: Charlie owns one flute, two horns, and a harp for a total of 1 + 2 + 1 = 4 instruments. Twice as many flutes as Charlie is 2 * 1 = 2 flutes,. Half as many horns as Charlie is 2 / 2 = 1 horn. Thus, Carli owns 2 + 1 = 3 instruments. Therefore, the combined total number of musical instruments owned by Charlie and Carli is 4 + 3 = 7 instruments.

A: 20
Step-by-step reasoning process: Angie earned 80 and paid 42 for necessities, so she had 80 - 42 = $38 left. Angie had 18 left after paying taxes, so her share of the taxes was 38 - 18 = $20 this month.
