Answer:
D. 15 percent
Explanation:
Cost of the machine = $2,000
Having considered operating costs as power, taxes, and so forth, the additional revenue from the output of this machine is expected to be $2,300
Expected return = $2,300 - $2,000
= $300
Therefore, the rate of returns
= Returns/cost
=300/2000
= 0.15
In Percentage, 15%. The expected rate of return on this machine is 15%
