Answer to Problem 25PPS

  n=$10

Explanation of Solution

Given:

Company A: $19.95+$0.21per text

Company B: $24.95+$0.16per text

Calculation:

Let the cost of 1 text message = n

Company A: 19.95+0.21n

Company B: 24.95+0.16n

Therefore,

  19.95+0.21n=24.95+0.16n24.95−19.95=0.21n−0.16n5=0.5nn=$10
