Mai invests $20,000 at age 20. She hopes the investment will be worth $500,000 when she turns 40. If the interest compounds cont
love history [14]

Answer:

\approx 17.5% per annum

Step-by-step explanation:

<u>Given:</u>

Money invested = $20,000 at the age of 20 years.

Money expected to be $500,000 at the age of 40.

Time = 40 - 20 = 20 years

<em>Interest is compounded annually.</em>

<u>To find:</u>

Rate of growth = ?

<u>Solution:</u>

First of all, let us have a look at the formula for compound interest.

A = P \times (1+\frac{R}{100})^T

Where A is the amount after T years compounding at a rate of R% per annum. P is the principal amount.

Here, We are given:

P = $20,000

A = $500,000

T = 20 years

R = ?

Putting all the values in the formula:

500000 = 20000 \times (1+\frac{R}{100})^{20}\\\Rightarrow \dfrac{500000}{20000} =(1+\frac{R}{100})^{20}\\\Rightarrow 25 =(1+\frac{R}{100})^{20}\\\Rightarrow \sqrt[20]{25} =1+\frac{R}{100}\\\Rightarrow 1.175 = 1+0.01R\\\Rightarrow R \approx17.5\%

So, the correct answer is \approx <em>17.5% </em>per annum and compounding annually.

What is the solution of the following system of linear equations? −21 + 15x = 6y −5x + 2y = −8 Select one: A. (15, -7) B. (4, 11
quester [9]

Answer:

C. No solution

Step-by-step explanation:

System of Equations:

A) -21+15x=6y

B) -5x+2y=-8

Simplifying and rearranging equation A.

Dividing each term by 3 (common factor for each term) in equation A.

\frac{-21}{3}+\frac{15x}{3}=\frac{6y}{2}

-7+5x=2y

Subtracting both sides by 2y

-7+5x-2y=2y-2y

-7+5x-2y=0

Adding 7 both sides.

-7+7+5x-2y=0+7

5x-2y=7  

Adding the above equation to equation B.

   5x-2y=7  

+ -5x+2y=-8

We have 0=-1

which is not true.

Hence the system has no solution. (Answer)
