Lucy purchased a prepaid phone card for $15 Long distance calls cost 16 cents a minute using this card. Lucy used her card only once to make a long distance call. If the remaining credit on her card is $10.52 , how many minutes did her call last?

Respuesta :

I think you do $15 x 16 cents = 900minutes / 16 cents = 60 minutes.

And then do $10.52 x 16cents = 168.32

Subtract 900-168.32 = 731.68minutes / 16cents= 45.73 minutes not used

60minutes - 45.73 =14.27min used.


Sorry if this isnt correct.
