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.

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.
