An executive invests $28000, some at 8% and the rest at 6% annual interest. If he receive annual return of $2000 how much is inv

Svetlanka [38]

Answer:

$16,000 at 8% annual interest.

$12,000 at 6% annual interest.

Step-by-step explanation:

Let x be amount invested at a rate of 8% annual interest and y be the amount invested at a rate of 6% annual interest.

We have been given that an executive invests $28000, some at 8% and the rest at 6% annual interest. We can represent this information as:

$x+y=28,000...(1)$

We are also given that he received annual return of $2000. We can represent this information as:

$(\frac{8}{100})x+(\frac{6}{100})y=2,000...(2)$

$0.08x+0.06y=2,000...(2)$

We will use substitution method to solve our system of equations. From equation (1) we will get,

$x=28,000-y$

Substituting this value in equation (2) we will get,

$0.08(28,000-y)+0.06y=2,000$

$2240-0.08y+0.06y=2,000$

$2240-2240-0.08y+0.06y=2,000-2240$

$-0.08y+0.06y=2,000-2240$

$-0.02y=-240$

$\frac{-0.02y}{-0.02}=\frac{-240}{-0.02}$

$y=12,000$

Therefore, the executive has invested $12,000 at a rate of 6% annual interest.

Upon substituting y=12,000 in equation (1) we will get,

$x+12,000=28,000$

$x+12,000-12,000=28,000-12,000$

$x=16,000$

Therefore, the executive has invested $16,000 at a rate of 8% annual interest.

Step-by-step explanation:

7(3x - 1) - (x + 5) = -52

21x - 7 - x - 5 = -52

20x = -52 + 12

20x = -40

x = -2
