If a bank charges $6.00 per month and $0.12 per check for one of its checking accounts, then the total monthly cost to write x checks is  and the average cost of each of the x checks written is  Compare these two formulas by filling in the following table. Round to the nearest cent.

Quizplus · Accepted Answer

- To find the total monthly cost to write x checks, we use the formula 
6 + 0.12x. For example, if x = 50, then the total monthly cost is 6 + 0.12(50) = $12.
- To find the average cost of each of the x checks written, we use the formula 
(6 + 0.12x)/x. For example, if x = 50, then the average cost per check is (6 + 0.12(50))/50 = $0.24.
- Option B is the only one that correctly shows both of these formulas in their simplified forms.
