0.09 or 9%
Explanation:
This question has some irregularities. The correct question should be :
Elinore is asked to invest $4,900 in a friend's business with the promise that the friend will repay $5,390 in one year's time. Elinore finds her best alternative to this investment, with similar risk, is one that will pay her $ 5,341 in one year's time. U.S. securities of similar term offer a rate of return of 7%. What is the opportunity cost of capital in this case?
Solution
Given from the question
Investment (I) = $4,900
Return on investment (ROI) in one year = $5,341
Rate or opportunity cost of capital r is given by
ROI = I × (1 + r)
input the given data
$5,341 = $4,900 (1 + r)
$5,341 = $4,900 + $4,900r
$5,341 - $4,900 = $4,900r
r = ($5,341 - $4,900) / $4,900
r = 0.09
Or 9% in percentage
