Question

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 1

your anwser is 28,000/700 = 40.

Answer 2

g = 28000 - 700t

Explanation:

Given,

The original quantity of the water in the pool = 28000

It is emptying 700 gallons per hour,

So, the total amount of water drained in t hours = 700t,

Also, the remaining water in the pool ( say g ) = Original quantity of the water - quantity drained in t hours

⇒ g = 28000 - 700t

Which is the required equation.
