Answer :
Answer:
A person needs to write 20 checks each month for bank A and B to charge the same amount of fees ($12).
Step-by-step explanation:
let number of checks be represented by c
Bank A equation = 10 + 0.10c
Bank B equation= 8 + 0.20c
Equate the above equations to each other and solve for c
10 +0.10c = 8 + 0.20c
Group numbers on one side and the variables on the other;
10 - 8 = 0.20c - 0.10c
2 = 0.10c
Divide both sides by c to get c = 20
If you plug in 20 for c in each equation, you'l get $12 in total fees for each bank, making their fees equal.
Therefore , a person needs to write 20 checks each month for bank A and B to charge the same amount of fees($12)
