Question

Raina purchased a prepaid phone card for $25. Long distance calls cost 8 cents a minute using this card. Raina used her card only once to make a long distance
call. If the remaining credit on her card is $22.84, how many minutes did her call last?

Answer 1

take 25-22.84=2.16/.08=27 minutes

Answer 2

Answer:

27 minutes.

Step-by-step explanation:

Start by finding the amount she used and not the amount she has left. She used $2.16. Divide this amount by .08 representing the cost per minutes and you will get 27 whole minutes as your answer. Hope this helps:)
