I would say that Christopher used a show and tell technique to demonstrate what he has made as that is the most effective way to reveal one's abilities is to see the outcome with one's own eyes and then how it was made makes much more sense than just describing it with only words.

The capital investment cost for a switchgrass-fueled ethanol plant with a capacity of 250,000 gallons per year is $2,000,000. Th

Answer:

$2,740,251.24

Explanation:

Applying power sizing technique or an exponential model to determine the cost of new boiler.

This model identify the cost variation along with change in capacity or power of the equipment.

$\frac{C_{A} }{C_{B} } =(\frac{S_{A}}{S_{B}})^{x}$

Where,

Cb = Cost of new plant

Sa = capacity of new plant

Sb = capacity of old plant

x = cost capacity factor

Therefore,

$\frac{C_{A}}{2,000,000} =(\frac{400,000}{250,000})^{0.67}$

$C_{A}=2,000,000\times\frac{400,000}{250,000}$

= 2,000,000 × 1.3701

= $2,740,251.24
