-Neither Company A nor Company B

Answer 1

9514 1404 393

Answer:

  company B

Step-by-step explanation:

The growth rate is 1 less than the growth factor. The growth factor is the base of the exponential term.

Company A

  growth factor: 0.70

  growth rate: 0.70 -1 = -0.30 = -30%

__

Company B

  growth factor: 1.90

  growth rate: 1.90 -1 = 0.90 = 90%

__

Company B has a higher growth rate than Company A. (Company A has decreasing sales, not increasing.)
