A leaky pool loses 2 1/4 inches of water each day. Jermaine and Mildred are asked to determine the change in the amount of water in the pool over 5 days.

Jermaine's Solution Mildred's Solution

5 (-2 1/4) 5 (-2 1/4)

5 (-2 - 1/4) 5 (-2 - 1/4)

-10 - 1/4 - 10 - 5/4

-10 1/4 - 11 1/4

Which describes the reasoning used to determine whose solution is correct?

A. Jermaine is correct because - 10 - 1/4 equals - 10 1/4.

B. Jermaine is correct because he distributed 5 correctly.

C. Mildred is correct because she multiplied 5 by - 2 but not by - 1/4.

D. Mildred is correct because she distributed 5 correctly.
