    The question is how many checks do you need to write per month to make the online banking service be a better deal? Let x = number of checks per month Local bank cost per month: 3 + 0.4x Online banking service cost per month: 9 3 + 0.4x = 9 Solve for x. If you write fewer than x checks per month, the local bank is a better deal. If you write x checks per month, they are the same. If you write more than x checks per month, the online banking service is a better deal.

    lets put it this way, put them into equations: the local bank: y=.4x+3 online bank: y=9x now plug in 12 for x and see which one would be better for banking. (which one is less?) :)

    all you have to do is put the 12 in for x and solve.. so it would be 4(12)+3 then you would do (4*12)+3 then do the same with the other one 9(12) and see which one is lower..
