What Sample Exam are you referring to? The NCEES 2011 Transportation Sample Questions and Solutions has none of the values you listed above.

I concur with JMT. #522 in the 2011 NCEES Transpo Sample Q&As is an engineering economics type question.

Ahh, ace means #533.

ace, the solution shown is correct.

The existing area is made up of 20AC Forest + 10AC Meadow + 18AC Residential + 2AC Commercial = 50 AC total

In the proposed condition, a 10AC Commercial site is being developed within the Forest portion. So, in the proposed condition, you'll have:

(20-10)AC Forest + 10AC Meadow + 18AC Residential + (2+10)AC Commercial = 50 AC total
