Janet invested $10,000, part at 2% and part at 12%. if the total interest at the end of the year is $600, how much did she invested at 2%

Answers

Janet invested $6000 at 2 %.

Let x = amount invested at 2 %. Then 10 000 - x = amount invested at 12 %

interest at 2 % + interest at 12 % = 600

0.02x + 0.12(10 000 – x) = 600

0.02x + 1200 – 0.12x = 600

0.10x = 600

x = 600/0.10 = 6000

Solve for x.

Option C is the correct answer.

Step-by-step explanation:

We need to find 25 x = 65

Dividing both sides by 25

We will get

                25x=65\n\n(25x)/(25)=(65)/(25)\n\nx=(13* 5)/(5* 5)\n\nx=(13)/(5)\n\nx=2.6\n\nx\approx 3

Option C is the correct answer.

The calculated value of x in the equation 2/5x = 6/5 is (c) 3

How to calculate the value of x in the equation

From the question, we have the following parameters that can be used in our computation:

2/5x = 6/5

Divide through the equation by 2/5

So, we have the following representation

(2x/5)/(2/5) = (6/5)/(2/5)

Evaluate the quotient on the right hand side

(2x/5)/(2/5) = 3

Lastly, we have

x = 3

Hence, the value of x in the equtaion is x = 3

4\left( 2x-2 \right) -4=4\left( x-5 \right) +32\n \n 8x-8-4=4x-20+32\n \n 8x-12=4x+12

\n \n 8x-4x=12+12\n \n 4x=24\n \n \frac { 1 }{ 4 } \cdot 4x=\frac { 1 }{ 4 } \cdot 24\n \n x=6
4(2x - 2) - 4 = 4(x - 5) + 32
4(2x) - 4(2) - 4 = 4(x) - 4(5) + 32
8x - 8 - 4 = 4x - 20 + 32
8x - 12 = 4x + 12
-4x       -4x       
4x - 12 = 12

     4x = 24
