Question

Shilpa's gym membership includes a one-time fee of $20. She then pays a discounted fee of $5 for each visit. The function that shows her average cost after x visits

Answer 1

`\text {average cost after x visit = } (20 + 5x)/(x)`

Answer 2

`(20+5x)/(x)`

Explanation:

Fixed cost = $20

She then pays a discounted fee of $5 for each visit.

Fees for x visits = 5x

So, Total fees after x visits = 20+5x

`Average = \frac{\text{Total fees}}{\text{No. of weeks}}`

`Average = (20+5x)/(x)`

Hence The function that shows her average cost after x visits is
`(20+5x)/(x)`
