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 Solution5(-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 1/4Which 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.
