Question 20 Linda purchased a prepaid phone card for $ 20 . Long distance calls cost 21 cents a minute using this card. Linda used her card only once to make a long distance call. If the remaining credit on her card is $ 10.76 , how many minutes did her call last?

44 minutes

Step-by-step explanation:

Calls = 21 cents per minute

Remaining credit after long distance call= $10.76

Total credit used  =$20- $10.76

                             = $9.24

Minutes her call lasted = $ 9.24

                                         $0.21

                                     = 44 minutes.
