Question

erin’s basic cell phone plan charges 54.99 for service plus 0.18 per minute beyond the included 500 minutes in the plan

Answer 1

To calculate how much she’ll be charged for (x) minutes, consider:

- if x is 500 minutes or less, she’ll only be charged the base 54.99 service fee
- if x is greater than 500, she gets the first 500 minutes included and charged 0.18 per minute beyond that. So subtract x - 500 to find out how many minutes she’ll be charged for and multiply that number by 0.18. Remember to add the base service fee.
