Answer:

If Jina purchased a card that was $15.00 for long distance calls and has $12.27 left, then we need to figure out how much she spent in that time period first

15.00-12.27= 2.73, Jina spend $2.73 on her last call

Now we want to take 2.73/0.21 to see how many minutes she spent on the call

2.73/0.21=13

Jina spent 13minutes on her last call

Hope this helps ;)
