10.) The realized income each week is $79.87. Add both payments and tips then deduct the tax deductions (multiply the rates to the gross income per week). Gross income per week: (4.70 + 3.85) x 13hrs = 111.15 Tax deductibles: 8.50 (FICA) + 13.67 (federal tax) + 9.11 (state tax) = (31.28) Realized income per week: 111.15 - 31.28 = 79.87
11.) The value of the stocks in its second year is $1,340.75. Multiply the investment by the percentage increase, then add the result to the investment. You can also use this formula = investment x (1 + %) First year: 1,050 x (1 + 0.13) = 1,186.50 Second year: 1,186.50 x (1 + 0.13) = 1,340.75
12.) a. The total value of your stocks after 2 years is $2,046. Use <em>investment x (1 - %)</em> in computing the decreases while <em>investment x (1 + %)</em> in computing the gains. First year: 2,000 x (1 - 0.07) = 1,860 Second year: 1,860 x (1 + 0.10) = 2,046
b. The balance in your savings account after 2 years is $2,150.74. Use this formula = investment x (1 + rate)^number of years Balance = 2,000 x (1 + 0.037)^2 = 2,150.74
