Ответ:
her call lasted for 22 minutes
Step-by-step explanation:
Rita purchased a prepaid phone card for $30. This means that the total credit on her card is $30. Long distance cost 16 cents a minute using the card. Converting to dollars, it costs 16/100 = $0.16
Rita used her card only once to make a long distance call. If the number of minutes if long distance call that she made is x, total cost of x minutes long distance calls will be 0.16 × x = $0.16x
The remaining credit on her card would be 30 - 0.16x
If the remaining credit on her card if $26.48, it means that
30 - 0.16x = 26.48
0.16x = 30 - 26.48 = 3.52
x = 3.52/0.16 = 22 minutes.
