A cellular offers a monthly plan of $15 for 350 min. Another cellular offers a monthly plan of $20 for 425 min. Which company offers the better plan?

Let's figure out the unit cost of minutes per dollar:

1. Plan 1: 350 minutes / $15 = 23.33 minutes per dollar
2. Plan 2: 425 minutes / $20 = 21.25 minutes per dollar

Plan 2 is better, because you get more minutes per dollar.
