4. Determine the amount of a $3000 investment at 9%/a compounded monthly for 6 years. [4 marks]
sweet [91]

Answer:

A = $ 5137.65 .

Step-by-step explanation:

Amount = $3000

interest rate = 9 %

                    = 9/12 = 0.75%  

compounded monthly for

time = 6 years.

       = 6 × 12 = 72 months.

A = P(1+\dfrac{r}{100})^t

A = 3000\times (1+\dfrac{0.75}{100})^{72}

A = $ 5137.65

hence, the amount after compounding $3000 at the rate of 9% after 6 years is  A = $ 5137.65 .

Inessa05 [86]

Answer:

\%Increase = 4\%

Step-by-step explanation:

Given

Initial\ Population = 625

Final\ Population = 650

Required

Determine the percentage population increase

This is calculated using the following formula:

\%Increase = \frac{Final - Initial}{Initial} * 100\%

\%Increase = \frac{650 - 625}{625} * 100\%

\%Increase = \frac{25}{625} * 100\%

\%Increase = \frac{25* 100\%}{625}

\%Increase = \frac{2500\%}{625}

\%Increase = 4\%

<em>Hence, there is a 4% increment from 2014 to 2015</em>
