Question

Write an equation or inequality for the following. Then solve for the unknown.

32. Francis joins a gym to shed a few pounds. He pays an initial membership fee of
$25.00 and agrees to pay $13.00 per week. After a while he decides to give it up. He
spent a total of $90.00. How many weeks was he a member?

Answer 1

Answer: 5 weeks hope this is right/helped

The total cost is the sum of the initial membership fee and the weekly fees:

25+13x=90

13x=90−25

13x=65

x-65/13

x=5

So, Francis was a member for 5 weeks.
