Answer:
(i) 2.71 years
(ii) 5.38 years
(iii) Never or 0
Explanation:
1. Payback period:
= Initial cost ÷ cash inflows
= 1625 ÷ 600
= 2.71 years(Approx).
2. Payback period:
= Initial cost ÷ cash inflows
= 3225 ÷ 600
= 5.38 years(Approx).
3. The payback period for an initial cost of $5,100 is a little trickier.
Notice that the total cash inflows after eight years will be:
= 8 × $600
= $4,800
Payback period
= Initial cost ÷ cash inflows
= 5100 ÷ 600
= 8.5
This answer does not make sense since the cash flows stop after eight years, so again, we must conclude the payback period is never.
Answer: network
Explanation:
Network externality simply states that demand for a good or service has to do with how other people demand for that particular good or service. It means consumer's buying patterns are influenced by the purchase of others buying the product.
Therefore, a network externality exists when the number of customers who purchase a good or use it influences the quantity demanded.
Answer:
take a complex, real-world issue and simplify it down to its essentials.
Explanation:
A theory can be defined as a simplified but abstract representation that gives a detailed relationship about the interaction between two or more variables.
Generally, the main purpose of a theory is to take a complex, real-world issue and simplify it down to its essentials. Thus, in economics, a theory gives a detailed explanation and an understanding of issues such as inflation, recession, taxation, etc and any problem associated with them.
In order to test theories, economists usually make use of economical models such as the production possibility frontier (PPF), Mundell-Fleming model, Classical model, Keynesian IS/LM model, Solow growth model, etc.
