Answer:
The correct answer is option d. whether the product has utility.
Explanation:
The demand elasticity is a concept that explains the elasticity of the consumer in terms of buying a product while its price rises.
All of the factors given in the question are a part of this concept except whether the product has utility.
The reason is that when a consumer buys something, the utility of that desire is not measured. If people have a high demand elasticity, they would buy the most priciest of things which have no utility as such.
Answer:
NPV = $100.4002 rounded off to $100.40
Explanation:
The NPV or net present value is the present value of a project or business's cash flows which are calculated by deducting the cash outflows from the cash inflows. NPV is a tool or criteria used for investment and project appraisal. The NPV can be calculated as follows,
NPV = CF1 / (1+r) + CF2 / (1+r)^2 + .... + CFn / (1+r)^n - Initial Outlay
Where,
- CF1, CF2, ... represents the cash flows in Year 1, Year 2 and so on.
- r represents the discount rate
NPV = 660 / (1+0.075) + [ -85 / (1+0.075)^2] - 440
NPV = $100.4002 rounded off to $100.40
Answer:
For more than 180 minutes of phone use.
Explanation:
Let m represent number of minutes of phone use in a month.
We have been given that in Plan A, there is no monthly fee, but the customer pays $0.06 per minute of use.
The cost of using m minutes in plan A would be
.
We are also told that in Plan B, the customer pays a monthly fee of $4.80 and then an additional $0.03 per minute of use.
The cost of using m minutes in plan B would be
.
To find the amounts of monthly phone when Plan A will cost more than Plan B, we will set cost of plane A greater than cost of plan B as:

Let us solve for m.




Therefore, Plan A will cost more than Plan B for more than 180 minutes of phone use.
