What single decimal multiplier would you use to decrease by 3% followed by a 6% increase?
Charra [1.4K]

Answer:

1.0282

Step-by-step explanation:

The multiplier for a increase of a% is 1 + a/100.

The multiplier for a decrease of b% is 1 - b/100.

Decrease of 3% followed by a 6% increase:

Calculate each multiplier, and then multiply then:

Decrease 3%: 1 - (3)/100 = 0.97

Increase 6%: 1 + (6)/100 = 1.06

0.97*1.06 = 1.0282

The answer is 1.0282
