Mai purchased a prepaid phone card for $20. Long distadnce calls cost 8 cents a minute using this card. Mai used her card only once to make a long distance call. If the remaining credit on her card is $16.16, how many minutes did her call last?

Answer

48 minutes and 2 sec

Explanation:

so every minute cost 8 cents so i toke the 20$ and kept subtracting 8 cents from it until i got to 16.14 and i knew i couldn't subtract another 8 cents because that would've been below 16.16 so i just added 2 sec and it gave me 16.16 and i counted all of the minutes. i hope i gave u the right answer because i tried and i´m very bad at math lol.

I'm not really good at math but I would like to help.

If each call is $.08, then the card can call last for 250 minutes.

The call lasted 202 minutes. Divide 16.16 by .08.
