A construction crew is lengthening a road. The road started with a length of 53 miles, and the crew is adding 3 miles to the road each day.
Let L represent the total length of the road (in miles), and let D represent the number of days the crew has worked. Write an equation relating L to D. Then use this equation to find the total length of the road after the crew has worked 31 days.
Equation:
Total length of the road after 31 days: -miles
