Based on the information below which project would be selected and why? Projects 1 has an initial investment of $50,000 and a net cash inflow of $27,000 for a period of 2 years. Project 2 has an initial investment of $150,000 and a net cash inflow of $59,000 in year 1 and $120,000 in year 2. The discount rate to be used is 5%Please create an objective true using these two solutions. Solution1 - More accommodation/residence should be built in the airport itself as it would allow Pascal to save a lot of time consumed while reaching the airport from his house. He would stay in the built-in residence only during his workdays and in his house on the weekend. It will also allow many passengers to stay if their flights get postponed/canceled due to any reason. Solution 2 - If a prayer room/area is built in the airport itself, it will allow Rajput and other diverse travelers and people who work in the airport to complete their prayer in its proper time. Rajput could complete that specific prayer between the time after he checks in his luggage and the boarding time.

A-B-C-D-E, A-F-E, A-B-H-J-K-E and A-S-T-E. Each activity in this network can be crashed by a maximum of 4 weeks. The crashing cost (per week), for the first week (crashing first time), for activity A is: $400, E is $415 and all other activities is : $100 (per week per activity). The crashing cost, second week and onwards(crashing second time), for activity A is $1000 per week, E is $1200 per week and for all other activities is $200 per activity per week.

- System projects are notorious for being late and over budget. When should management stop a project that is late or costing more than the intended budget? Consider this case: Valley Enterprises opted to implement Voice over Internet Protocol (VoIP) service in its Phoenix, Arizona, service area. The company has 15 locations in the Phoenix area, all with local area networks and all with secure Wi-Fi connections. The company’s current phone system was designed and implemented in the 1950s, when Valley operated in three locations. As more locations were added, standard telecommunications solutions were implemented, with little thought devoted to compatibility. Over the years, phone services were added as new buildings and facilities arose. Valley CEO Doug Wilson heard of VoIP at a trade show and contacted TMR Telecommunications Consultants, requesting a bid. TMR spent a week with the CIO of Valley Enterprises, gathering data, and submitted a bid for $50,000 in late 2007.…Randall Systems in considering four projects A, B, C and D that have risks associated with the producing benefits.

Thetechnical group’s best estimate is that the hardwareMantel_c04.indd 138 9/6/2016 4:52:35 PMcosts will be $125,000 if the Window’s option is pursued.

Setting up the production facilities to beginproduction would cost $50,000 for toy 1 and $80,000 for toy 2. Once these costs arecovered, the toys would generate a unit profit of $10 for toy 1 and $15 for toy 2. Thecompany has two factories that are capable of producing these toys.

For administrative reasons, the same factory would be usedfor both new toys if both are produced. Toy 1 can be produced at the rate of 50 per hourin factory 1 and 40 per hour in factory 2. Toy 2 can be produced at the rate of 40 perhour in factory 1 and 25 per hour in factory 2. Factories 1 and 2, respectively, have500 hours and 700 hours of production time available before Christmas that could beused to produce these toys.
