a family swimming pool membership costs $45 per month plus a one-time registration fee of $35. if a family has paid a total of $395, how many months have they been members?

8 months

Step-by-step 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
