Question

(a) A local bookseller is considering expanding store space to increase his capacity for books. The rent for the additional space would cost $3000 per year. The bookseller predicts that the added space will pull in an additional profit of $4000 per year. The current interest rate is 12%. Should the bookseller invest in the extra space

Answer 1

Yes

Step-by-step explanation:

Profit = Revenue - Cost

In this case, the cost of renting the additional space is $3000 and it’s gain from it is $4000. Hence, the additional space alone provides a profit of $1000 ($4000 - $3000). The expected rate of return from this investment is : (1000/3000) x 100 = 33.3% whilst the marginal cost is only a 12% interest rate. Hence, it is wise to invest in the additional space for the bookstore.
