Question

The following table shows the expressions that represent the sales of 4 companies: Company A B C D Sales 170(1.04)x 330(1.80)x 250(0.06)x 120(1.09)x Rank the company sales by smallest to largest percent of increase and select the correct answer below.

Answer 1

We are given the table that represents the sales of 4 companies:

Company        Sales
 A                    170 * 1.04x
 B                    330 * 1.80x
 C                    250 * 0.06x
 D                    120 * 1.09x

assuming x is the number of years of the company, and x is the same for all four. 

We can simplify the equations:

A = 176.8x
B = 594x
C = 15x
D = 130.8x

Percentage increase ranking (smallest to largest):

C, D, A, B. 

As the number of years increases, the company sales also increases accordingly. 

Answer 2

C, D, A, B. or C,A,D,B
