Teresa purchased a prepaid phone card for $15 . Long distance calls cost 24 cents a minute using this card. Teresa used her card only once to make a long distance call. If the remaining credit on her card is $3.96 , how many minutes did her call last?

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

step-by-step explanation:

here's what happens:

1) the graph of f   = x^2 is shifted 2 units to the right.

2) the resulting graph is reflected in the x-axis, so that the parabola now opens down.

3) this final result is transformed up by 5 units.

answer: the answer is e
