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 .

Solve for x<br><br> 2x+21/3 =5

Jlenok [28]

x = -1

Simply get the variable on one side of the equation alone and simplify:

2x = 5 - 21/3

2x = 15/3 - 21/3

2x = -6/3

2x = -2

x = -1
