Answer:

3400, Rise, C

Explanation:

1. Since there are just 3 firms and two already has a sum total of 70% (40+30), the third firm will have a market share of 30%

HHI= [tex]40^{2}+ 30^{2}+30^{2}\\[/tex]

HHI= 1600+900+900

HHI= 3400

2. Abe's Bikes with 30% leaves the market, if the two firms were to share Abe's market share equally (15+15), it will leave Firm A with 55% (40+15) and Firm B with (30+15) 45%

Therefore,

HHI= [tex]55^{2}+45^{2}[/tex]

HHI=3025+2025

HHI= 5050

A rise in HHI

3. C

An index of 10,000 corresponds to a monopoly firm with 100% market share.
