Question

a small inflatable pool holds 10 gallons of water. a tiny leak causes the amount of water in the pool to change by -0.05 gallon each hour until the pool is empty what is the total change in the amount of water

Answer 1

I'm not sure I understand to well but if its asking how many hours till its empty it would be 200 hours

Answer 2

200 hours.

Explanation:

A small inflatable pool that holds the amount of water = 10 gallons

A tiny leak causes the change in water = -0.05 gallon

Since quantity is with negative notation that represents that quantity of the water is reducing.

Let it takes x hours to empty the pool.

Therefore, amount water leaked in x hours = 0.05x gallons

And this amount is equal to 10 gallons.

0.05x = 10

x =
`(10)/(0.05)`

= 200 hours

Therefore, in 200 hours pool will be emptied.
