Answer 1

Answer:

a) y = -500x + 130,000

b)67,500 gallons remaining

c) 260 hours

Step-by-step explanation:

Since water is being removed at a rate of 500 gallons per hour, the slope would be a negative.

a) y = -500x + 130,000

For part b input 125 for x:

y = -500(125) + 130,000

y = 67,500

There are 67,500 gallons remaining

For part c we are solving for the x intercept

0 = -500x + 130,000

Subtract 130,000 from both sides

-130,000 = -500x

x = 260

It will take 260 hours for the pool to completely drain
