Answer:

Step-by-step explanation:

checking account A : monthly fee of 20 and transfer fee of 3 per transfer

20 + 3t

checking account B: monthly fee of 30 and transfer fee of 2 per transfer

30 + 2t

when will they cost the same....when will they be equal....so set them equal and solve for t

20 + 3t = 30 + 2t

3t - 2t = 30 - 20

t = 10 <===== they will be equal at 10 transfers
