Jared made a 15 minute phone call yesterday that cost $0.90. how long will jared be on the phone today if the call cost $1.32, assuming the rate of the cost remains constant

1. figure out cost per min

.90/15 =.06/min

2. figure out mins. since we know cost per min we can divide that by jared’s total cost for that call

1.32/.06= x mins ——->22 mins
