Question 11
A company had beginning retained earnings \$63,100. During the year, the company reported sales \$127,800, costs of goods sold \$89,900, depreciation \$11,200, dividends \$28,000, and interest expenses \$3,400. The tax rate is 35%. What is the retained earnings balance at the end of the year?
a. \$50,245
b. \$76,425
c. \$68,455
d. \$75,445
e. \$53,615

We first calculate the net income
Sales 127,800
Costs 89,900
Depreciation 11,200
Interest 3,400
Total Expenses 104,500
Income before tax 23,300
Tax (35%) 8,155
Net Income 15,145
Ending Retained Earnings = Beginning Retained Earnings + Net Income - Dividends
= 63,100 + 15,145 - 2,800
= 75,445

Question 12
A company is considering remodeling a building which they own. The remodeling costs are estimated at \$1,420,000. The building contains 75 rentals units. The company will increase the rent on each unit such that his total rental income increases by \$400,000 a year for the next 5 years. At a discount rate 15%, what is the benefit of the remodeling project to the company?
a. -\$32,145.91
b. -\$46,767.61
c. -\$49,922.17
d. -\$79,137.96
e. -\$76,824.57

The benefit is = 400,000 X PVIFA (5,15%) - 1,420,000
= 1,340,862.04-1,420,000
= -79,137.96

Question 13
A company is investing \$259,000 in a new project. The firm expects the project will produce cash flow \$50,000 a year for the first two years, and \$80,000 a year for the following three years. How long will it take the ...
