Question

A construction crew is lengthening a road that originally measured 44 miles. The crew is adding 1 mile to the road each day. The length, L (in miles), after d days of construction is given by the following function.

L(d)= 44+d
What is the length of the road after 35 days?

Answer 1

The length of the road after 35 days is of 79 miles.

Explanation:

The length of the road, after d days, is given by:

`L(d) = 44 + d`

What is the length of the road after 35 days?

This is l when d = 35. So

`L(35) = 44 + 35 = 79`

The length of the road after 35 days is of 79 miles.
