Suppose that the monthly cost of a long-distance phone plan (in dollars) is a linear function of the total calling time (in minutes). When graphed, the function gives a line with a slope of 0.13. See the figure below. The monthly cost for 41 minutes of calls is $15.34. What is the monthly cost for 46 minutes of calls? Monthly cost 15.34 (in dollars) Calling time (in minutes) $0 Suppose that the monthly cost of a long-distance phone plan (in dollars) is a linear function of the total calling time (in minutes).
