Suppose you are filling a backyard swimming pool with a regular garden hose which has a flow rate of 17 gallons per minute. If it takes 11.67 hours to fill the pool, what is the volume of the pool in cubic meters?

8.75

how-to:

first, we need to find what we have to work with.

since i know that we have 7 (years) and 0.8 (inches), we can use these to solve and find the equation!

secondly, what you want to do, is see that we need to know how much growth out of the 0.8 inches he got in only 1 year, instead of 7 years.

let's try to divide.

7 ÷ 0.8 = 8.75

she made 48 + y = a cookies.     not enough info is given to find the total.
