The Final Investment Value is $\$10,309.12$

The interest earned is $\$4,309.12$

Step-by-step explanation:

The compound interest formula is equal to

$A=P(1+\frac{r}{n})^{nt}$

where

A is the Final Investment Value

P is the Principal amount of money to be invested

r is the rate of interest in decimal

t is Number of Time Periods

n is the number of times interest is compounded per year

in this problem we have

$t=8\ years\\ P=\$6,000\\ r=0.07\\n=1$

substitute in the formula above

$A=6,000(1+\frac{0.07}{1})^{1*8}$

$A=\$10,309.12$

Find the interest earned

I=A-P

$I=\$10,309.12-\$6,000=\$4,309.12$

x = 200

Step-by-step explanation:

Plug in 15 as y into the equation and solve for x:

1/5x - 2/3y = 30

1/5x - 2/3(15) = 30

1/5x - 10 = 30

1/5x = 40

x = 200

So, when y = 15, x = 200
