Answer 1

Rank the company sales by the smallest to the largest percentage of increase.

Step-by-step explanation:

The given table represents the sales of 4 companies:  

Company       Sales

A                    170 × 1.04(X)

B                    330 × 1.80(X)

C                    250 × 0.06(X)

D                    120 × 1.09(X)

• Let us assume x is the number of years of the company, and the value of X is the same for all.

• The simplified equation is

A = 170 × 1.04(X) = 176.8X

B = 330 × 1.80(X) = 594X

C = 250 × 0.06(X) = 15X

D = 120 × 1.09(X) =  130.8X

• The company sales from the smallest to the largest percentage of increase:

⇒ C(15), D(130.8), A(176.8), B(594)

• An increase in the number indicates the increasing percentage of the company.

• Therefore, the correct option is C, D, A, B.
