Answer:
$181
Explanation:
You'll use the given equation:
c = 90 + 7m
to find the total cost of the ticket. In order to solve for c you must first solve for m. Since m is the number of miles over the posted speed limit, you will subtract
63 - 50 = 13
So m will equal 13. Now that you solved for m you would simply plug it in to the equation.
c = 90 +7m
c = 90 + 7(13)
c = 90 + 91
c = 181
