Let m = the number of miles
A: y = .30m + 100
B: y = .40m + 40
.30m + 100 = .40m + 40
60 = .10m
600 miles = m

m represents the number of miles
100 + 0.30m = 40 + 0.40m
Can you solve for m and answer?
Inactive Tutor
100 + 0.30m = 40 + 0.40m
60 + 0.30m = 0.40m subtract 40 from both sides
60 = 0.10m subtract 0.30m from both sides
600 = m divide both sides by 0.10
