Answers
c = 40 * n + 0.20 * m <--- part b
if n = 5 and m = 330
c = 40 * 5 + 0.20 * 330
c = 200 + 66 = $266 <-- part a
296 = 200 + 0.20 m
96 = 0.20 m
m = 960/2 = 480 miles <---- part c
if n = 5 and m = 330
c = 40 * 5 + 0.20 * 330
c = 200 + 66 = $266 <-- part a
296 = 200 + 0.20 m
96 = 0.20 m
m = 960/2 = 480 miles <---- part c
