Unformatted text preview: different models. One model has a purchase price of $278.00 and will cost $17.00 per month to operate. The initial cost of the second model is $413.00 but because of the higher energy factor rating, it will cost an average of $11.00 a month to operate. a. Set up a table to compare the two heaters. b ) Use the table to write equations for the two models. Heater 1has the equation c = 17m + 278 and Heater 2 has the equation c = 11m + 413, where c is the cost per month and m is the number of months c. Graph the equations. What do you see? ) Month Heater 1 Heater 2 0 $278. $413. 1 $295. $424. 2 $312. $435. 3 $329. $446. Riser (R) Tread (T) 0 60 1 58 2 56 3 54 equation: T = 2R + 60...
