3.10 PART 3

After 13.33 ATM fees, you will be paying the same amount of money in fees at both banks. Because you cannot use the ATM 13.33 times, we can say the two banks will never have the EXACT same fees.

y=3.25x y=3.25(13.33) y=43.32

3.25x=2.5x+10 0.75x=10 x=13.33

First National Bank fees: y=2.5x+10 Liberty Bank fees: y=3.25x

x = number of ATM transactions y = total fees paid
