Cameron pays $0.95 per song with his current music service. Cameron’s friend tells him of another service that has a $15 joining fee but charges $0.80 per song. At what number of songs does this new service become a less expensive option than Cameron’s current service?

on monday rodney ate 1/4th of the sandwich = 3/12

on tuesday he ate 1/3rd of the sandwich = 4/12

therefore in total he has eaten = 3/12 + 4/12 = 7/12

thus we can say that he has eaten 7/12 of the sandwich on monday and tuesday alltogether.
