tow company A charges $50 + m and company C charges 80 + .1m. If both companies charged the same, how far are you from your garage? Are they asking for 2 different #? If so,I am 30 miles from A and 0 miles from C. Correct?

the problem asks: "If both companies charged the same"

meaning that 50+m = 80+.1m
30 = .9m
m = 33 1/3 miles

50+33.333 = 80 + 3.333
