During the summer, the height of the water in the pool decreased by 5 inches each week due to evaporation. What is the change in the height of the water over an 8 week period?

40 inches

Step-by-step explanation:

We know that the height of water in a pool decreased 5 inches per week.

This means that we can form the equation , since the amount of water remaining is proportionate to the amount of weeks that have passed.

We know , since we need to find the change for 8 weeks.

The change will be the absolute value of -40, which just makes it positive, so 40.

Hope this helped!

for this case we have the following expression:

to solve, we rewrite the expression as:

we apply double c and we have:

thus, the quotient is 48.

so, patel found a wrong ratio and the multiplication was incorrect.
