A furniture rental company charges a fixed amount plus a fee based on the number of days for which the furniture is rented. The graph below shows the amount paid for a different number of days to rent the furniture:

A graph titled Furniture Rentals plots the Number of Days on the x axis and the Amount in dollars on the y axis. A straight line joins the ordered pairs 0, 80 and 4, 240.
What is the fixed amount charged? (5 points)

A: $20

B: $40

C: $60

D: $80

1 answer

B: $40

To find the fixed amount charged, we look at the y-intercept of the line on the graph, which is the point where the number of days is 0. In this case, the y-intercept is $80. This means that the fixed amount charged by the furniture rental company is $80.
