Answer : 2. "Analogous"
Explanation :
Answer: B) Analogous Explanation: Richard is using an estimate based on a project very similar to to his own with staff he will be using. Answer A is incorrect because perametric modeling involves using a mathematical model to predict costs, such as dollars per line of code. Answer C is incorrect, although close; if the development project is a common item, such as putting down new flooring, a rule -of-thumb measurement can be used, although it is less accurate. Answer D is incorrect because it is not a form of estimating, but a type of pricing.
