Question

Molly's basic cell phone plan charges $35.99 for Service Plus $0.25 per minute beyond the included 250 minutes in the plan how much would it cost Molly if she used her cell phone for 400 minutes in one month

Answer 1

The answer I got is $73.49. Here's the work:

400 min - 250 min = 150 used over the limit

Equation: 35.99 + .25(x) = total

Replace the value of "x": 35.99 + .25(150) total

After doing the calculations I got $73.49. Hope that helps :))

Answer 2

First, you would subtract the original 250 minutes from 400, equaling 150 extra minutes. For each of those minutes, it costs 25 cents, so you multiply 0.25 * 150, and your answer is 37.5, or $37.50. You then add the $37.50 to the original cost of $35.99, and your answer should be $73.49.
