Aroad that must be 40 ft. wide with a tolerance of 18 in a. |w+1.5| < 40 b. |w+40| < 1.5 c. |w-1.5| < 40 d. |w-40| < 1.5

Hello there!

We know that the road must be 40ft wide with a tolerance of 18 inches;

First, lest convert the 18 inches into feet.

we know that 1 ft is equivalent to 12 inches,

then 18 inches is equivalent to 18/12 = 1.5 feet

Then the road must be of 40 ft with a tolerance of 1.5 feet; this means that the road can be between 38.5 feet and 41.5 feet

Then he correct model is that the width of the road minus 40 feet must be less than 1.5 (this means that the diference between the wedith of the road and 40 ft is smaller than the tolerance)

this is: IW - 40ftI < 1.5ft

Then the right answer is the option D
