I would depend on how many minutes are used.
20 + .05 (x - 500) ≤ 30
Solve for x, then compare
Your current cell phone company charges $30 per month for unlimited minutes. Another company charges $20 per month for the first 500 minutes plus 5¢ a minute for any additional minutes. Should you keep your current service or switch to the other company?
