Question

A company rents diving equipment for a fixed amount plus a fee based on the number of days for which the equipment is rented. The table below shows the total charges, y, in dollars, of renting diving equipment for x number of days:

Diving Equipment Rentals
Number of Days
(x) Total Charges (dollars)
(y)
0 5
1 20
2 35


What is the fixed amount charged?
$2
$5
$15
$20

Answer 1

B. 5

Explanation:

To find the fixed fee, we need to make x=0. When x=0 y=5 so the fixed charge is 5.

Answer 2

The answer is B. $5

*i got an 100 on this test so i'm positive

Notice how the description says "a fixed amount plus a fee based on the number of days." And the question only asks for the fixed amount, not including the fee.

For the first rental, they had only been renting but had not kept it for a day yet, so the fee is not added and there is only the cost of the fixed amount for the equipment, which is $5. This shows that when they keep the equipment for a day, the fee is $10 added on each day the equipment is kept.

So, taking away the fee for the numbers of days, the points would be (0,5), (1,10), (2,15). Add on another $10 per day onto the y colomn and you get the table we have here.

Good luck on your quiz, hope you understood all of that :)
