Biometric
authentication is a security feature used in computer science that

Answer:
orange juice 0.80 dollar
Bagel 1 dollar
coffe 0.60 dollar
Explanation:
We construct the equation system:
We subtract one from another to get an expression without C:
1.5A+1.2B+C - (A+B+C) = 3 - 2.40
0.5A + 0.2B = 0.6
Then, we solve in the first part to express B as an expression of A
considering the coffe is worth half of the new cost of A
C = 1.5A / 2 = 0.75A
A + B + C = 2.40
A + B + 0.75A = 2.40
B = 2.40 - 1.75A
And now we replace in the other expression to get A:
0.5A + 0.2(2.40 - 1.75A) = 0.6
0.5A - 0.35A + 0.48 = 0.60
0.15A = 0.12
A = 0.12/0.15 = 0.8
Now we solve for C:
C = 0.75A = 0.6
Last, for B:
A + B + C = 2.40
0.8 + B + 0.6 = 2.40
B = 2.40 - 0.8 - 0.6 = 1
Answer:
Oligopoly.
Explanation:
An oligopoly can be defined as a market structure comprising of a small number of firms (sellers) offering identical or similar products, wherein none can limit the significant influence of others.
Hence, it is a market structure that is distinguished by several characteristics, one of which is either similar or identical products and dominance by few firms.
The characteristics of an oligopolistic market structure are;
1. Mutual interdependence between the firms.
2. Market control by many small firms.
3. Difficult entry to new firms.
According to the concentration ratio, when a small number of companies control more than 40 percent of a market, it is called an oligopoly.
