What single decimal multiplier would you use to decrease by 12% followed by a 4% increase

The single decimal multiplier is 0.9152

Step-by-step explanation:

Here, we want to write a single decimal number that would work as to decrease an original value by 12% and increase it also by 4%

Let the original value be x

12% = 12/100 = 0.12

So decreasing by 12% would be x-0.12x = 0.88x

Now this 0.88x, we shall increase it by 4%

4% is same as 0.04

Thus by increasing, we have;

0.88x + 0.04 (0.88x)

= 0.88x + 0.0352x = 0.9152x

So the single factor we are multiplying by is 0.9152
