Question

A construction crew is lengthening a road. The road started with a length of 52 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 31 days

Sure :)

Answer 8

what was the initial length? and what was the number of days?

Answer 9

52 to begin with while adding 3 miles x day

Answer 10

so it would be L = 52 + 2D, now they are asking for 31 days so we would have to plug it in the equation then it would be L = 52 + 2(31) =

Answer 11

L=114
?

Answer 12

that's right.
