Solution and Explanation:
The yYearly Equal Cash Inflows =[tex](110-44-28) * 1500-8000[/tex] = 46000
Present Value of Inflows at the rate of 10% = [tex]$46000 * \text { PVIFA( } 5 \text { years }, 10 \%)$[/tex]= 46000 multiply with 3.791 = 174386
NPV = 174386 minus 132500 = 42386
Briggs must make an investment in the project as it generates additional wealth and NPV is positive
For NPV = 0, PV of inflows = 132500
PV Of Inflows = Annual Cash Flow multiply with 3.791
Annual Cash Flow = 132500 divide by 3.791 = 34951.20
So, Hours =[tex](34951.20+8000) /(110-46-28)[/tex] = 1193.08 hours
