If x = the number of minutes, then, from the problem description you can write:
0.36+%2B+0.21x+%3C=+3 Solve this inequality for x. Subtract 0.36 from both sides.
0.21x+%3C=+2.64 Now divide both sides by 0.21
x+%3C=+12.57minutes.
A person could talk for almost 13 minutes without exceeding a cost of $3.00
