How would you answer this question using the casio fx$-9750$GII

A new electronic process monitor costs $$7,000,000.$ This cost could be depreciated at $30\%$ per

year $($CCA Class $10).$ The monitor could be sold for $$1,428,595$ at the end of five years. The new

monitor would save the firm $$2,400,000$ before taxes in annual operating costs for the five years.

There would be no impact on net working capital. The firm's weighted average cost of capital is

$15\%$ and the corporate tax rate is $40\%.$

What would be the NPV of purchasing this system?

A$)$ $$866,886$

B$)$ $$816,957$

C$)$ $$3,310,960$

D$)$ $$92,891$

E$)$ $$512,639$

How would the NPV of purchasing the monitor change if we were to use a higher CCA rate

$($for example, $40\%$ instead of $30\%)?$

A$)$ The NPV of purchasing the monitor would decrease.

B$)$ The NPV of purchasing the monitor would increase.

C$)$ The NPV of purchasing the monitor would not be affected.

D$)$ There is not enough information to answer this question.

E$)$ None of the above.
