is given in the attachment.

Explanation:

first case

a) It decrease their price by 27.87%

b) Her revenues increased by 33.44%

second case

a) the demand decrease by 43.32‬%

b) revenues decreases by -0.2432%

Explanation:

-3.05 = 0.85 / change in price

change in price = 0.85 / 3.05 = 0,278688 = 27.87%

Revenues change:

Revenue = Q x P

Q = (1 + 85%)

P = (1 - 27.87%)

1.85 x 0,7213‬ = 1,334405‬

Before revenues where 1 (100%)

Revenues increased by 1.334405 - 1   = 0.334405 = 33.44%

Second case:

variation in demand

0.57 = Change in demand / 0.76

0.57 x 0.76 = Change in demand = 0,4332‬

change in revenue

Q = (1 - 0.4332)

P = (1 + 0.76)

revenue (1 - 0.4332)(1 + 0.76) = 0,5668‬ x 1.76 = 0,997568‬

0.997568 - 1 = -0,002432‬ = -0.2432%
