A partially filled pool contains 600 gallons of water. A hose is turned on, and water flows into the pool at the rate of 8 gallons per minute. How many gallons of water will be in the pool after 70 minutes?

1160 gallons.

This situation can be modeled by the equation y = 8x + 600, where y is the number of gallons of water in the pool and d is the number of minutes that have passed.

40 gallons

Explanation:

the rules is - 8x + 600 = y becuase every minute 8 gallons is empty and theres 600 to begin with

x is the number of minutes and y is the numbers of gallons

so you do - 8 times 70 plus 600

which will gove you 40
