Anna is in a phone booth with $1.35 in change. a call home costs 60 cents for the first five minutes and 15 cents for each additional minute. How long can she talk?

Respuesta :

for 10 minutes, if she has 5 minutes to talk we would subtract 60 cents from 1.35 leaving us with 75 cents, so that could be split up into 15 cents 5 times making it 5 more minutes. so she can talk for 10 minutes
I believe she can talk for 11 min bc 60.0 times 2 is 1.20 and when u add 15.0 you get 1.35
