Question

A family swimming pool membership costs $32.50 per month plus a one- time registration fee of $25. If a family has paid a total of $252.50 , how many months have they been members.

Answer 1

The family took swimming pool membership for 7 months

Solution:

Given, A family swimming pool membership costs $32.50 per month plus a one- time registration fee of $25

A family has paid a total of $252.50

We have to find how many months have they been members.

The total paid amount is given as:

`\text { total paid amount }=\text { membership cost } * \text { number of months }+\text { one-time registration fee }`

`\begin{array}{l}{252.50=32.50 * \text { number of months }+25} \\\\ {32.50 * \text { number of months }=252.50-25} \\\\ {32.50 * \text { number of months }=227.5} \\\\ {\text { Number of months }=(227.5)/(32.5)=7}\end{array}`

Hence, the family took membership for 7 months.
