Answer:
The call lasted for 47 minutes.
Step-by-step explanation:
It is given that:
Value of prepaid card = $25
Cost per minute of long distance call = 24 cents = $0.24
Remaining credit = $13.72
Let,
x be the number of minutes
y be the remaining amount
y = 25 - 0.24x
13.72 = 25 - 0.24x
0.24x = 25 - 13.72
0.24x = 11.28
Dividing both sides by 0.24
Therefore,
The call lasted for 47 minutes.
