D. A monthly service fee of $1.00 and a per-check fee of $1.00.

Answer 1

C. A monthly service fee of $0.50 and a per-check fee of $1.00.

Step-by-step explanation:

Step 1:

The graph represents the number of checks written per month on the x-axis and the total monthly fees on the y-axis.

There is a monthly service fee and a personal check fee.

To determine the monthly service fee, we determine the value of y when x = 0.

To determine the personal check fee, we calculate the difference between the values of y when x varies.

Step 2:

When $x=0, y = 0.50$ so when the number of checks written is zero, the price is $0.50. This is the monthly service fee.

When

$x=1, y = 1.50$,

$x=2, y=2.50$

$x=3, y=3.50.$

So for every unit change in x, the y values also change by $1. So the personal check fee is $1.

So a monthly service fee of $0.50 and a per-check fee of $1.00, which is option C.
