Juliette [100K]

Answer:

The amount invested at 10% rate is $ 2200

Step-by-step explanation:

Given as :

The total amount earn by student = $6500

The total interest received at the end of year = $607

Let the amount invested at 10% rate = $x

So, The amount invested at 9% rate = ($6500 - $x)

Let the time for which money invested = 1 year

Now from Simple Interest method :

SI = $\frac{principal\times Rate\times Time}{100}$

Or, SI_1 + SI_2 = $\frac{x\times 10\times 1}{100}$ + $\frac{(6500-x)l\times 9\times 1}{100}$

Or, SI_1 + SI_2 = $(\frac{10x}{100})+\frac{(6500-x)\times 9}{100}$

Or, $607 × 100 = 10x + (6500-x) × 9

Or, $60700 = 10x- 9x + 58500

Or, $60700 - $58500 = x

Or , 2200 = x

∴ x = 2200

So, The amount invested at 10% rate = $x = $ 2200

Hence The amount invested at 10% rate is $ 2200 Answer

1) C
2) A
3) D

Explanation: 
1) Voluntary deductions are amounts that you elect to come out of your paycheck every pay period. Federal tax is not voluntary; neither is state tax, nor Social Security. The only voluntary deduction in this list is health insurance. You are not obligated to pay for your health insurance by automatically withholding it from your check.

2) FICA is the tax that goes towards Social Security and Medicare. It is involuntary, and it is deducted as a percentage of your gross (pre-withholding) pay.

3) A fixed expense would be one that is the same from month to month. The only one of these expenses that would be the same amount monthly is a mortgage.
