What is the answer to x-8-n

It is x-8-n

Step-by-step explanation:

because you cant do anything with the letters or the number so the equation stay the same

Tammy has charged $17 + $36 + $11 = $64 in total.
So Tammy has to pay $64 before she have interest charged to her.
If the APR is 21% then monthly interest is 21% / 12 = 1.75%
So if she don't pay those $64 by the end of month, she will have to pay $64 + $64 * 0.0175 = $64 + $1.12 = $65.12.
