Question

Kala purchased a prepaid phone card for $25. Long distance calls cost 8 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 $21.48, how many minutes did her call last?

Answer 1

44 minutes

Explanation:

25.00-21.48=3.52

this means she used $3.52

which is 352 cents.

Each minute is 8 cents so 352/8 = 44
