Question

Doughnuts cost $3.45 for a dozen at Store A, and cost $2.40 for 8

at Store B. Which store has a cheaper cost per doughnut?

Answer 1

store A is cheaper

Explanation:

All right. If you divide Store A's numbers like so,

3.45 / 12, you'd get about 0.28, which is the average cost per one donut at store A.

For store B, if you divided,

2.40/8, you'd get 0.30, which is the average cost per one donut at store B, which means that store A is cheaper!
