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

$\text {average cost after x visit = } \dfrac{20 + 5x}{x}$

Answer 2

Answer:

$\frac{20+5x}{x}$

Step-by-step 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

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

$Average = \frac{20+5x}{x}$

Hence The function that shows her average cost after x visits is $\frac{20+5x}{x}$
