Answer:
8 months
Explanation:
Let the number of months of membership be represented by x
Total amount paid = $395
A family swimming pool membership costs $45 per month plus a one-time registration fee of $35.
Hence:
395 = 35 + 45x
We subtract 35 from both sides
395 - 35 = 35 - 35 + 45x
360 = 45x
x = 360/45
x = 8 months
Hence, they have been members for 8 months
