An owner can lease her building for $160,000 per year for three years. The explicit cost of maintaining the building is $55,000, and the implicit cost is $70,000. All revenues are received, and costs borne, at the end of each year. If the interest rate is 5 percent, determine the present value of the stream of:. a. Accounting profits.
b. Economic profits.

a. Accounting profits.

Account profit = Revenue - explicit cost

= 160,000 - 55,000

= $105,000

Present value of $105,000 per year for 3 years is:

= 105,000 * Present value interest factor of an Annuity, 3 years, 5%

= 105,000 * 2.7232

= $285,936

b. Economic profit

Economic profit = Revenue - explicit cost - implicit cost

= 160,000 - 55,000 - 70,000

= $35,000

Present value of $35,000 per year for 3 years:

= 35,000 * Present value interest factor of an Annuity, 3 years, 5%

= 35,000 * 2.7232

= $95,312

Note: The profits were treated as annuities as they were constant.

i believe it’s b because the rest don’t make sense

say it in english maybe we can
