Question

texaschic101 · Answer

5 + .50b = 48.50
.50b = 48.50 - 5
.50b = 43.50
b = 43.50/.50
b = 87

check...
5 + .50(87) = 48.50
5 + 43.50 = 48.50
48.50 = 48.50 (correct)

If I did this correctly, Thomas paid 87 bills. You might need to get a second opinion on this.

As long as the service doesn't charge $5 per month, which it doesn't state that, then I think it is correct.
