Jessica purchased a prepaid phone card for $20. Long distance calls cost 23 cents a minute using this card. Jessica used her card only once to make a long distance call. If the remaining credit on her card is $11.26, how many minutes did her call last?

The card has $20.

A long distance call costs $0.23.

20 - 11.26 = 8.74 (the amount deducted from her balance).

8.74 / 0.23 = 38 minutes (we divide that amount by the cost).

y = 0.77(x)

step-by-step explanation:

the jacket retains this value after 23% cut or retains 77% of original value. plug original 87 jacket price for x and the remaining value should be y.
