Question

A bank charges $0.25 per check and its monthly fees are $10. If Jerome issues 10 checks in a month, how much will a monthly checking account cost him?

Answer 1

For this case, the first thing we must do is define variables.
We have then:
x: number of checks.
y: total cost.
We now write the linear function that represents the problem.
We have then:

`y = 0.25x + 10`
Then, Jerome issues 10 checks in a month.
Therefore, we evaluate the function for x = 10.
We have then:

`y = 0.25 (10) + 10 y = 2.5 + 10 y = 12.5`
Answer:
a monthly checking account will cost him about:
y = 12.5 $

Answer 2

Multiply 0.25 per check by 10 checks and then add that to the monthly fee of $10.

0.25 x 10 = $2.50 for 10 checks.

$10 + $2.50 = $12.50 total per month.
