There are already 1,600 gallons of water in a swimming pool. If water is filling the pool at a rate of 25 gallons per minute, which expression indicates the amount of water, in gallons, in the swimming pool after m minutes?

Question

A.
1,600 - 25 × m
B.
1,600 ÷ 25 × m
C.
1,600 + 25 × m
D.
(1,600 + 25) ÷ m

Answer 1

The correct expression to indicate the amount of water, in gallons, in the swimming pool after \( m \) minutes is:

C. \( 1,600 + 25 \times m \)

This is because you start with 1,600 gallons and add 25 gallons for each minute that passes.
