Martina purchased a prepaid phone card for $15 . Long distance calls cost 8 cents a minute using this card. Martina used her card only once to make a long distance call. If the remaining credit on her card is $11.48 , how many minutes did her call last?

44 minutes

Step-by-step explanation:

With regards to the above information, we can calculate the minutes in which Martina's call lasted as shown below;

We can make y represent the minutes

15 - 8y/100 = 11.48

15 - 0.08y = 11.48

15 - 11.48 = 0.08y

0.08y = 3.52

y = 3.52/0.08

y = 44

It therefore means that Martina's call lasted for 44 minutes.
