Question

Convert each percent increase or decrease into a multiplier show work

a. 5 percent increase
b. 12 percent decrease

Answer 1

a. 1.05

b. 0.95

Explanation:

a. 5 percent increase

5% = 0.05

Because it is increasing, so we add 1

1 + 0.05 = 1.05

b. 12 percent decrease

12% = 0.12

Because it is decreasing, so subtract 1

1 - 0.05 = 0.95

So, the answer is

a. 1.05

b. 0.95
