Question

A manager of a tanning salon charges a flat fee of $5 per visit plus $1.50 for every hour spent in the tanning bed. The equation y = 5 + 1.5x represents the total fee, y, for visiting the salon, where x is the number of hours spent. Which of the following best represents the interpretation of the y-intercept in this equation?

A. It represents the cost per hour spent in the tanning bed.
B. It represents the total fee for spending zero hours in the tanning bed.
C. It represents the fixed fee for visiting the salon regardless of the hours spent.
D. It represents the total fee for spending one hour in the tanning bed.

Answer 1

The y-intercept represents the fixed fee for visiting the salon regardless of the hours spent.

Step-by-step explanation:

The y-intercept is 5 (a = 5). It represents the fixed fee for visiting the salon regardless of the hours spent. In other words, even if a customer spends zero hours in the tanning bed, they will still be charged $5 for the visit.
