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
