Answer:
b. Each decision variable must be non-negative in the optimal solution.
Explanation:
This constraint or restriction states that x11, x12, x21, and x22 all must be at least 0 or greater. in other words, they cannot be negative numbers. If the restriction had been > (greater than), then it would mean that all the variables must be positive numbers. But since it is ≥ (greater than or equal to), 0 is a valid option.
Answer:
The answer is 8 years
Explanation:
FV= PV(1+r)^n
Where
PV= let's assume PV is $100
FV = Since FV will be doubled, the we have $200($100 x 2)
n= ?
r= 9percent
Let us use the rule of 72 which states that an investment will double when:
Annual Investment Rate x Number of Years = 72.
Number of years = 72/9
= 8 years
The investment is doubled in 8 years at the rate of 9percent
Answer:
B. Consumers
Explanation:
In business, consumers are the most vulnerable groups. Governments have enacted fraud laws to safeguard the rights of consumers. As enterprises seek profits, the laws seek to hold sellers accountable for the products or services they provide.
The laws provide mechanisms for consumers to fight back against abusive business practices. If unchecked, sellers may take advantage of consumers' ignorance and low bargaining power.
<u>Solution and Explanation:</u>
(a). Firm in perfect competition produces at minimum efficient scale, MEC where average cost AC is minimum. The price is determined by the market supply and demand.
(b) Note that q1 is at the minimum of AC while Q* is to the left of q1. Similarly, P1 is equal to MC while P* is higher than MC. This shows that firms in perfect competition produce more and charge less than the firms in monopolistically competitive market.
(c) All firms in monopolistically competitive market as well as perfectly competitive market earn zero economic profit in the long run. This is because there is a free entry and exit
(d) Demand is steeper for firms in monopolistically competitive market so that demand is elastic. Demand is horizontal for any quantity which means it is perfectly elastic for a firm in competitive market.
