Question

this is the call plan for minna's cell phone $15 a month plus $0.20 per minute of call time. Minna made 30 minutes of calls this month and 110 texts. How much does she have to pay the phone company?

Answer 1

To solve this you would do the following:

We know her plan is $15/monthly, regardless of any additional texts/calls she makes.

If 1 minute = $.20 worth of money, we would simply multiply 30 (she made 30 minutes worth of calls) x $.20 ($.20 for each minute). The product is $6.

So, $15 + $6 = $21.

Unless the amount owed per text is mentioned and you forgot to include it in the title, you would not need to take this into consideration.
