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:
[tex]\text { total paid amount }=\text { membership cost } \times \text { number of months }+\text { one-time registration fee }[/tex]
[tex]\begin{array}{l}{252.50=32.50 \times \text { number of months }+25} \\\\ {32.50 \times \text { number of months }=252.50-25} \\\\ {32.50 \times \text { number of months }=227.5} \\\\ {\text { Number of months }=\frac{227.5}{32.5}=7}\end{array}[/tex]
Hence, the family took membership for 7 months.
