Q: A company sells a product for $$150. The cost to produce the product is 100. $$What is the percentage markup on cost?

$$Markup = \frac{150 - 100}{100} \times 100\% = 50\%$$

Q: A business borrows $5,000 at a simple interest rate of 6% per year for 3 years. What is the total interest paid?

$$I = 5,000 \times 0.06 \times 3 = 900$

Q: A retailer offers a 20% trade discount on a product with a list price of $500. What is the net price after the discount?

$$Net\ Price = 500 - (500 \times 0.20) = 400$

Q: A business invests $2,000 at an annual compound interest rate of 5% for 4 years. What is the future value of the investment?

$$FV = 2,000 \times (1 + 0.05)^4$ = 2$$,431.01$

Question 1

A business is considering two investment projects. Project A requires an initial investment of $$10,000 and will return 12$$,000 after one year. Project B requires an initial investment of $$10,000 and will return 13$$,000 after two years. If the annual interest rate is 5%, which project has the higher present value?

Accepted Answer

Project A, because $$PV = \frac{12,000}{(1+0.05)^1$} = 11$$,428.57$$ and Project B, PV$$ = \frac{13,000}{$$(1+0.05)^2$$} = $$11,793.39$$, so Project B has the higher present value.

Question 10

Which of the following best describes the difference between gross and net profit?

Accepted Answer

Gross profit is total revenue minus cost of goods sold; net profit is gross profit minus operating expenses and taxes.

Question 11

A company’s financial statement shows total revenue of $$50,000, cost of goods sold of 30$$,000, and operating expenses of $10,000. What is the net profit?
