Explanation:
Given : A 28,000-gallon swimming pool is being drained using a pump that empties 700 gallons per hour.
i.e, Remaining gallons = 28,000- 700 × Number of hours.
Let g be the number of gallons remaining in the pool and t is the amount of time in hours the pool has been draining.
Then, the equation models this situation will be :-
