2N + 5 = N + 8

2N - N = 8 - 5

N = 3

Let M be the number of minutes we are looking for

We will express everything in cents

If the second plan is prefereable, it must be cheaper than the first....so.....we have his inequality

3995 + 8M < 19M

3995 < 19M - 8M

3995 < 11M

3995/11 < M

363.18 < M

At about 364 minutes, the second plan is cheaper
