Question

The cost for a pool membership for a family at a community pool is $350 plus $125 per month. A family paid a total of $1,350. How many

months did the family use the pool?

a-11
b-14
c-8
d-12

Answer 1

The family used the pool for 8 months

Explanation:

We know that the family paid a total amount of $1,350 dollars. We also know that they had to pay $350 dollars for joining the community pool. Lastly, they paid a monthly fee of $125 dollars. The value "x" represents months.

With that being said, here's our equation.

350 + 125x = 1,350

Subtract 350 from both sides and you should get this:

125x=1,000

Finally, divide 125 from both sides to get the x value.

x=8
