Checking account a charged a monthly fee of $5 and a per-check fee of $0.25, and checking account b charged a monthly fee of $6 and a per-check fee of $0.15. how many checks would anperson have to write for the two accounts to cost the same? a. 10 b. 25 c. 35 d. 20

First we need to know both the formula of A and B.

The formula of A is
C = 5 + 0.25p
with C representing total cost and p representing the amount of checks.

The formula of B is
C = 6 + 0.15p
with C representing total cost and p representing the amount of checks.

To find the point where A and B cost the same, we solve the following equation:
5 + 0.25p = 6 + 0.15p

Collecting terms gives us
-1 = -0.1p

Now we have to divide by -0.1 and we get.
10 = p
p = 10

So our after 10 checks both accounts cost the same amount of money. Answer A.
