70+.20D<=50+.60D
.20D-.60D<=50-70
-.40D<=-20
D>=-20/-.40 NOTE THE SIGN CHANGE DUE TO DIVIDING BY A NEGATIVE VALUE.
D>=50 MILES WILL MAKE THE 2 COMPANIES EQUAL.

I see the other tutors don't agree.
a=70+.2m
b=50+.6m
set them equal
70+.2m=50+.6m
20=.4m
multiply by 10
200=4m
200/4=50 the break even point is 50 miles
after that a is the better deal
