Aconstruction 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 31 days.

Step-by-step explanation:

(a) At 3 miles per day, after D days, the added length is 3D miles. When that is added to the original length, the total length is ...

  L = 53 + 3D . . . . miles

__

(b) When D=31, the length is ...

  L = 53 + 3·31 = 53 +93 = 146 . . . . miles
