8. A public swimming pool holds 250,000 gallons of water and is being
drained at a rate of 200 gallons per minute. The function g = -200m +
250,000 represents how many gallons remain in the pool g, after any
number of minutes m. How much more water remains after 5 minutes than
after 20 minutes?​

Respuesta :

Answer

Step-by-step explanation:

first substitute 5 into the eqation

(-200x5)+250,000=g

multiply

-1000+250,000=g

subtract and substitute

g=249,000

next

substitue in 20

(-200x20)+250,000=g

multiply

-4000+250,000

subtract and substitute

g=246,000

Answer :

3,000 Gallons

Step-by-step explanation :

Using the formula the question gave :

g = -200m +  250,000

-200 × 20 ( minutes ) + 250,000 = 246,000

-200 × 5 ( minutes ) + 250,000 = 249,000

How much more water remains after 5 minutes than

after 20 minutes ?​

249,000 - 246,000 = 3,000

Hopefully this helps ! Should be pretty easy if you have a calculator, next time break down the question :)
