Question

A construction crew is lengthening a road. The road started with a length of 59 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 34 days.

Equation:

Total length of the road after 34 days: ____miles

Answer 1

L = total length

D = number of days

they add 3 miles per day which = 3D

equation:  L = 59 +3D

 if they worked for 34 days, replace D with 34 to get:

L = 59 +3(34) =

L=59 + 102

L=161 miles total length after 34 days
