Question

The water level in a well decreased by 6 inches every month due to evaporation. What is the change in the water level after a six month period of time? ​

Answer 1

Explanation:

we don't know what level it was originally at so well use a variable for the unknown number. If you take 6 inches and do that 6 times for each month you will have 36 inches lost so w= water i = inches

w-(6i x 6) = 36

This isn't the best explanation but I hope this helps you
