Sanjay is comparing the cost of cell phone services. The phone he wants costs $50 at Dover Cellular, and the unlimited calling plan through their carrier would cost $3 per day. At Garrison Electronics, Sanjay could purchase the same phone for $60 and also get an unlimited calling plan for $2 per day. After some number of days, the two options would end up having the same total cost. What would the total cost be?
