ou just got a cellular phone for your birthday and are trying to decide on the best cellular phone company. When you contacted the Calls-A-Lot company, they were offering a monthly plan of $40 for 500 minutes and $0.25 for each minute over the 500 minutes. In the Sunday paper you see an ad for the TalkAway company, which offers a monthly plan of $35 for 500 minutes and $0.30 for each minute over the 500 minutes. LOOK AT THIS; How many minutes would you have to talk over the 500 minutes for the cost to be the same with both companies? What would be the equal cost?

OpenStudy (kymber):

You need to find the equations for each company and then plug in numbers over 500 to see when they'll equal the same thing
