Answer:
The single decimal multiplier is 0.836
Step-by-step explanation:
In this question, we are concerned with using a single decimal multiplier to denote a 12% decrease followed by a 5% decrease.
Let the number we want to decrease be x
A 12%(12/100 = 0.12) decrease means x - 0.12x = 0.88x
Now, we want to follow this up by a 5% decrease(5% = 5/100 = 0.05)
5% decrese of 0.88x is 0.88x - 0.05(0.88x)
= 0.88x - 0.044x = 0.836x
Thus, the single decimal multiplier that reflects a 12% decrease followed by a 5% decrease is 0.836
