Question 62107 • WV-Algebra I CR

A 28,000-gallon swimming pool is being drained using a pump that empties 700 gallons per hour. Which equation models this situation if g is the number of gallons remaining in the pool and t is the amount of time in hours the pool has been draining?

Answer
A
28,000 = –700t
B
28,000g = –700t
C
g = 700t – 28,000
D
g = 28,000 – 700t

Explanation

The pool starts with 28,000 gallons, and it loses 700 gallons each hour. After t hours, the amount remaining is the starting amount minus 700t, so g = 28,000 − 700t. This is choice D.
