A 28,000-gallon swimming pool is being drained using a pump that empties 700 gallons per hour. Which ec models this situation if g is the number of gallons remaining in the pool and t is the amount of time in hours
has been draining?
28.000 = -700t
28,000g = -7000
g = 700t - 28.000
0 g = 28.000 – 700t
