Answer 2

Answer:

20000X100/105

Step-by-step explanation:

To get the solution, we are looking for, we need to point out what we know.

1. We assume, that the number 20000 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 20000 is 100%, so we can write it down as 20000=100%.

4. We know, that x is 105% of the output value, so we can write it down as x=105%.

5. Now we have two simple equations:

1) 20000=100%

2) x=105%

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:

20000/x=100%/105%

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