Question

A construction crew is lengthening a road. The road started with a length of 54 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 39 days.

Answer 1

53+3(D) = L

53 + 3(38) =L

53 +114 = L

167=L
