That is true, hope that helps !
Answer:
(a) It will have multiple IRRs
(b) The MIRR calculated is 10.18% . Going by MIRR result , this project will only generate returns that is equal to cost of capital(10%) .If there are other avaible more viable projects, it should be rejected ( Please see attached computation).
Explanation:
(a) The multiple IRRs occurs when cash flows change sign and result in more than one value for the IRR.
Application of IRR to value an investment is only suitable when the project has normal cash flows, i.e a negative initial cash flow (i.e initial investment) followed by a series of positive cash flows.
In this scenario, we have negative cash flow of $6m in year 4 which occured after positive cash flow of $3.5m per year from year 1 to 3. This typically make IRR unreliable. To overcome this limitation , we can use Modified Internal Rate of Return (MIRR)
(b) Please see attached for more details.
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.
