Question

Thirty-six gallons of water (-36) splashed out of the pool yesterday. Today ten gallons were lost (-10). What was the total effect on the amount of water in the pool?

Answer 1

Let x = the amount of water in the pool

Splashed water = -36

Lost water = -10

Therefore:

$x-36-10=x-46$

Answer: There are 46 gallons less water in the pool.
