A construction crew is lengthening a road. The road started with a length of 56 miles, and the crew is adding 2 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 37 days. Equation: Total length of the road after 37 days: miles

Solution

Initial length of the road =56 mi

L= Total length

D= Number of days worked

Number of miles added in 1 day= 2 miles

Therefore,

L=56+D*2

After 37 days,

L=56 +(37*2)

L=130 miles.
