Answer:
46 minutes
Step-by-step explanation:
Teresa purchased a prepaid phone for $15
Long distance calls cost 24 cents a minute using this card
She used the card just once to make a long distance call
The remaining credit on her card was $3.96
Therefore the minutes in which her call lasted can be calculated as follows
Let x represent the minutes
15 - 24/100x= 3.96
15-0.24x= 3.96
-0.24x= 3.96-15
-0.24x= -11.04
x= 11.04/0.24
x = 46
Hence Teresa call lasted for 46 minutes
