Answer:

12.5%

Step-by-step explanation:

1. We assume, that the number 43200 is 100% - because it's the output value of the task.

2. We assume, that x is the value we are looking for.

3. If 43200 is 100%, so we can write it down as 43200=100%.

4. We know, that x is 12.5% of the output value, so we can write it down as x=12.5%.

5. Now we have two simple equations:

1) 43200=100%

2) x=12.5%

where left sides of both of them have the same units, and both right sides have the same units, so we can do something like that:

43200/x=100%/12.5%

6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for what is 12.5% of 43200

43200/x=100/12.5

(43200/x)*x=(100/12.5)*x - we multiply both sides of the equation by x

43200=8*x - we divide both sides of the equation by (8) to get x

43200/8=x

5400=x

x=5400

now we have:

12.5% of 43200=5400

SOLUTION

B = [tex]\frac{P}{R}[/tex]

[tex]\\[/tex]

[tex]\frac{n}{100}[/tex] = [tex]\frac{5,400}{43,200}[/tex]

[tex]\\[/tex]

n × 43,200 = 43,200n

100 × 5,400 = 540,000

540,000 ÷ 43,200n = 12.5%
