Tele has a cell phone that she uses only for emergencies. The cost of the phone is $60 a month. The cellular company is offering unlimited nights and weekends for an additional $10 a month ($120 a year). Tele thinks it would be "cool" to have this benefit and, after all, $10 a month is not much. Show Tele how much she will have in 20 years if she invests this $120 a year at 12% instead of accepting the unlimited nights and weekends offer.
