The FICA taxes for someone who is not self-employed and earns $120,000 would be $8,064. This is calculated by taking 7.65% of the first $102,000, which is $7,803, and then adding 1.45% of the remaining $18,000, which is $261. Therefore, the total FICA taxes would be $7,803 + $261 = $8,064.

The formula to calculate the future value of a loan with simple interest is A = P(1 + rt), where A is the future value, P is the principal, r is the interest rate, and t is the time period. Plugging in the given values, A = $3000(1 + 0.07*2) = $3000(1 + 0.14) = $3000(1.14) = $3420. Therefore, the correct answer is $3420.

To find 24% of 170, we can multiply 170 by 0.24. This calculation gives us 40.8, which is the correct answer.

To calculate the amount needed to put in the CD, we can use the formula for simple interest: Interest = Principal * Rate * Time. In this case, the interest is $3000, the rate is 6.5%, and the time is 2 years. Rearranging the formula, we get Principal = Interest / (Rate * Time). Plugging in the values, we find Principal = $3000 / (0.065 * 2) = $3000 / 0.13 = $23076.92. However, we need to find the amount to put in the CD now, so we need to discount this amount back two years. Using the formula for compound interest, we get Principal = Future Value / (1 + Rate)^Time. Plugging in the values, we find Principal = $23076.92 / (1 + 0.065)^2 = $23076.92 / 1.139225 = $20249.13. Therefore, the correct answer is $2654.87.

The original price of the exercise machine is $860. The sale price is calculated by subtracting 12% of the original price from the original price. 12% of $860 is $103.20. Subtracting $103.20 from $860 gives us $756.80, which is the sale price of the machine.

The loan's future value is $2150 and the principal borrowed is $2000. The time period for the loan is 1 year. To determine the simple interest rate, we can use the formula: r = (A - P) / (P * t) * 100. Plugging in the values, we get r = (2150 - 2000) / (2000 * 1) * 100 = 150 / 2000 * 100 = 0.075 * 100 = 7.5%. Therefore, the correct answer is 7.5%.

The simple interest owed for the use of the money can be calculated using the formula: Simple Interest = Principal (P) x Rate (r) x Time (t). Plugging in the given values, we have: Simple Interest = $4000 x 6% x 1 year = $240. Therefore, the correct answer is $240.

The correct answer is 5 because if we let x represent the unknown number, we can set up the equation 3 = 0.6x. By dividing both sides of the equation by 0.6, we find that x = 5. Therefore, 3 is 60% of 5.

To find the percentage, we divide the given number (18) by the total number (90) and multiply by 100. So, (18/90) * 100 = 20%. Therefore, 18 is 20% of 90.

The correct answer is $12,799.22. This can be calculated using the formula for compound interest: A = P(1 + r/n)^(nt), where A is the final amount, P is the principal, r is the interest rate, n is the number of times interest is compounded per year, and t is the number of years. Plugging in the values given, we get A = 12000(1 + 0.065/4)^(4*1) = $12,799.22. This is the amount of money that will be in the account after 1 year. The interest earned can be calculated by subtracting the principal from the final amount, which is $12,799.22 - $12,000 = $799.22.

The local sales tax rate is 6%, which means that for every dollar spent, 6 cents will be paid as tax. Therefore, to calculate the tax paid for a car worth $32,800, we multiply the purchase price by the tax rate: $32,800 x 0.06 = $1,968.

The percent decrease of the sale price from the regular price can be found by calculating the difference between the regular price and the sale price, which is $380 - $266 = $114. Then, divide this difference by the regular price ($380) and multiply by 100 to get the percentage decrease: ($114 / $380) * 100 = 30%. Therefore, the correct answer is 30%.

To calculate the amount that should be deposited now, we can use the formula for compound interest: A = P(1 + r/n)^(nt), where A is the future value, P is the principal amount, r is the annual interest rate, n is the number of times the interest is compounded per year, and t is the number of years.

In this case, the future value (A) is $500,000, the annual interest rate (r) is 7%, and the interest is compounded monthly (n = 12). The worker plans to retire in 35 years (65 - 30 = 35).

Plugging in these values into the formula, we can solve for the principal amount (P). The correct answer is $43,456.

The account's effective annual yield is 3.82%. This means that if you leave your money in the account for one year, you will earn a return of 3.82% on your initial investment. The interest is compounded daily, which means that the interest is added to the account balance every day, allowing for more compounding and increasing the overall yield.

The table for 7.2 indicates the tax owed for a single person with no dependents based on their taxable income. In this case, the taxable income is $18,000. By referring to the table and rounding to the nearest cent, the calculated tax owed is $956.25.
