Question

Question 3 Kala purchased a prepaid phone card for $30 . Long distance calls cost 13 cents a minute using this card. Kala used her card only once to make a long distance call. If the remaining credit on her card is $25.06 , how many minutes did her call last?

Answer 1

$30.00-$25.06=$4.94. Kala used $4.94 on her card for the last call. 13cents per minute, divide 4.94/13=38, her last call 38 minute.

Answer 2

her call lasted 12 minutes
