What single decimal multiplier would you use to decrease by 13% followed by a 6% decrease?

0.8178

Step-by-step explanation:

To make a 13% decrease in a value, we need to make the difference between the value (X) and 13% of the value:

X - 13% of X = X - 0.13*X = 0.87*X

To make a 6% decrease, following the same method, we just need to multiply the value by (1-0.06) = 0.94

So, to represent in a single decimal value a decrease of 13% and then a decrease of 6%, we just need to multiply the value by 0.87 and then by 0.94:

X*0.87*0.94 = X*0.8178

So the single decimal multiplier is 0.8178
