A construction crew is lengthening a road. The road started with a length of 51 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 33 days.

    Total length after 33 days will be 117 miles

    Step-by-step explanation:

    A construction crew is lengthening a road. The road started with a length of 51 miles.

    Average addition of the road is = 2 miles per day

    Let the number of days crew has worked are D and length of the road is L, then length of the road can represented by the equation

    L = 2D + 51

    If the number of days worked by the crew is = 33 days

    Then total length of the road will be L = 2*33 + 51

    L = 66 + 51

    L = 117 miles

    Total length of the road after 33 days of the construction will be 117 miles.
