Question 1168418: A construction crew is lengthening a road that originally measured miles. The crew is adding one mile to the road each day.
Let L be the length (in miles) after D days of construction.
Write an equation relating L to D . Then use this equation to find the length of the road after 36 days.

You can put this solution on YOUR website!
Originally WHAT length was the road? Call this Q.

In general, L=D%2BQ

Specifically for known D=36, you have L=36%2BQ.
Still a variable expression, because you were not given that Q.
