Ashley purchased a prepaid phone card for $15. Long distance calls cost 9 cents a minute using this card. Ashley used her card only once to make a long distance call. If the remaining credit on her card is $11.04, how many minutes did her call last?

x=6 and x=3

beep beep imma sheep

what i would say the best answer is a. 40.5

4.5(4 − x ) + 36 = 202 − 2.5(3x + 28) now multiply from the paranthesis

18 -4.5x + 36 = 202 -7.5x + 70 will add the numbers

54-4.5x = 272-7.5x move x to the left and numbers to the right

7.5x-4.5x = 272-54 make the difference

3x = 218 and divide by 3

x= 72
