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 so when the number of checks written is zero, the price is $0.50. This is the monthly service fee.

When

,

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.

step-by-step explanation:

because 1/3 is a fraction. we can tell because there is a divisor symbol between the 1 and the 3. if we were to add 2 fractions together, we would add the numerators, which is the number on top, but not the denominators, which is the number on the bottom

1/3+1/3=2/3

hope this !
