please help one math problem
A construction crew is lengthening a road. The road started with a length of 53 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 38 days.

L=53+3D
"L" is the total length
"3D" represents 3 miles times the # of days worked

so length is 167
OpenStudy (anonymous):
eq
53+3(D) = L
OpenStudy (anonymous):
yes
53+3(38)= L
so L= 167
OpenStudy (anonymous):
which one do i use this one
53+3(D) = L or yours?
OpenStudy (anonymous):
both are the same. you just rearranged the equation
