the complete question in the attached figure
we know that
A leaky pool loses 2 1/4 inches of water each day
Determine the change in the amount of water in the pool over 5 days
distribute the 5 to both -2 and -1/4
5*(-2 1/4)
5(-2 1/4) = 5(-2 + -1/4) = 5(-2) + 5(-1/4) = -10 + -5/4 = -10 + -1 1/4 = -11 1/4
the answer is
D. Mildred is correct because she distributed 5 correctly.
