Yes, that is the correct formula to calculate the cost of a call. Now, we need to set up an inequality representing the number of minutes a person could talk without exceeding $3.
Let m represent the number of minutes talked. So, the inequality should look like this:
0.36 + (m - 1) * 0.21 ≤ 3
Let m represent the number of minutes talked. So, the inequality should look like this:
0.36 + (m - 1) * 0.21 ≤ 3
