Question

What single decimal multiplier would you use to increase by 15% followed by a 17% decrease?

Answer 1

0.9545

Explanation:

Let an integer be x.

If x is increased by 15%, then the value of the number would be

115/100x=1.15x

If 1.15x is decreased by 17%, then the value of the number would be:

(100-17)/100×1.15x

83/100×1.15x=0.9545x

15 % increase

• 1.15 times

17% decrease
