Solution

Given:
• Factory workers were paid $20 per hour in 1990 and$10 per hour in 2000
• CEO was paid $5 million per year in 1990 and$50 million per year in 2000

To find:
• The percent increase in the CEO’s pay was what percent greater than the percent decrease in the factory workers’ hourly pay

Approach and Working:
• The percent decrease in the hourly pay of factory workers = $$\frac{(20 – 10)}{20} * 100 = 50%$$
• The percent increase in the CEO’s pay = $$\frac{(50 – 5)}{5} * 100 = 900%$$
• The percentage by which 900 is more than 50 = $$\frac{(900 – 50)}{50} * 100 = 1700%$$

Hence, the correct answer is option D.

A) 850%

B) 900%

C) 950%

D) 1,700%

E) 1,900%

First, let’s calculate the percent decrease for the workers, using the formula (New - Old)/Old x 100:

(10 - 20)/20 x 100 = 50% decrease

Next we calculate the percent increase for the CEO:

(50,000,000 - 5,000,000)/5,000,000 x 100

45,000,000/5,000,000 x 100

9 x 100 = 900% increase

Thus:

(900 - 50)/50 x 100

850/50 x 100 = 1700%
