Question

Susan purchased a prepaid phone card for $20. Long distance calls cost 24 cents a minute using this card. Susan used her card only once to make a long-distance call. If the remaining credit on her card is $9.92, how many minutes did her call last?

Answer 1

Answer:

42 minutes

Step-by-step explanation:

20 - 9.92 = 10.08

Susan used $10.08 to make her phone call

10.08/0.24 = 42

Her call lasted 42 minutes
