Dewayne is comparing two checking accounts, one has a monthly fee of $7 and a per-check fee of $0.30, and the other has a monthly fee of $4 and a per-­check fee of $0.40. what is the minimum number of checks dewayne needs to write for the first bank to be a better option? show your work.

Answer 1

If Dewayne writes 31 checks, he will pay a fee of $16.30 (.30x31 = 7) for the first banking option, but he will pay $16.40 (.40x31 = 4) for the second option, so he must write 31 checks for the first option to be the better option.
