Respuesta :

Answer:

correct option is 0.23

Explanation:

given data

sales =  $90 million

account A sale = $15 million

account B sale = $3.5 million

account C sale = $1.3 million

account D sale = $0.8 million

solution

we get her first total sale that is

total sale = $15 + $3.5 + $1.3 +  $0.8

total sale = $20.6 million

so

four-firm concentration ratio is = [tex]\frac{total \ account\ sale }{industry\ sales}[/tex]    ..............1

four-firm concentration ratio is = [tex]\frac{20.6}{90}[/tex]

four-firm concentration ratio is = 0.228 = 0.23
