Answer:
The company A has the largest percent of increase.
Step-by-step explanation:
The sales of two companies A and B are given as
[tex]S(A) = 260(1.9)^{x}[/tex] ......... (1) and
[tex]S(B) = 275(0.89)^{x}[/tex] ......... (2)
Now, for x = 0 to x = 1, the sale value of company A will be given by equation (1) as 260 and 260 × 1.9 = 494.
So, the percentage of increase is [tex][\frac{494 - 260}{260}] \times 100 \% = 90\%[/tex]
Again, for x = 0 to x = 1, the sale value of company B will be given by equation (2) as 275 and 275 × 0.89 = 244.75.
So, the percentage of decrease is [tex][ \frac{275 - 244.75}{275}] \times 100 \% = 11\%[/tex]
Therefore, the company A has the largest percent of increase. (Answer)
