The information provided is as below:
| Initial Cost | $ 2000000 | 
| Monthly O & M cost | $ 340000 | 
| Monthly Revenue | $380000 | 
| Salvage value | $ 122000 | 
| life | 72 months or 6 Years | 
| Interest rate | 6% per annum compounded monthly | 
The net present worth (NPW) is given by:
NPW = Sum of PV of Net Cash Inflow for each month up to 6 years
Net Cash Inflow = Cash Inflow - Cash Outflow
PV of Net Cash Inflow = Net Cash Inflow/(1+(6%/12))^n
Where,
n = nth month
Thus, the NPW of the given investment is:
| Month | Initial Cost (Cash Outflow)  | 
O & M Cost (Cash Outflow)  | 
Revenue (Cash Inflow)  | 
Salvage Value (Cash Inflow)  | 
Net Cash Inflow (Cash Inflow - Cash Outflow)  |

Thus, NPW = Sum of PV of Net Cash Inflow for each month up to 6 years is $498773.4539
Since, the net present worth is positive, the music network should make this investment.
