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
So a diver went 25.65 ft BELOW so it's negative. then he went 16.5 ft further down, so that's negative also. he then rose 12.45 ft, so that's positive. so the expression is: -25.65+-16.5+12.45, the answer is 23.7
