Luxury bus Service must replace cars every 5 years at a cost of $450,000. The company is considering depositing $4,000 at the end of each month at 8% per year compounded monthly.

Max and Adam are shopping for a new home. They can afford a down payment of $60,000 and monthly payments of at most $2,500.

(b) (6 marks) Kate and Miles ultimately make a downpayment of $50,000 on a $300,000 home and finance the balance through Creative Financing Inc. at 8.25% per year compounded monthly for 30 years. What monthly payments should Kate and Miles make to pay off the house? (c) (8 marks) Referring to part (b), use EXCEL to set up an Amortisation Schedule for the first 12 months of the loan. Attach the printout or copy your EXCEL amortisation into your assignment submission. EXCEL Instructions: Please refer to the amortisation example in Week 3 lecture notes and Topic 3 in the EXCEL Booklet . (d) (3 marks) Referring to the Amortisation Schedule from part (c), how much interest in total will Kate and Miles pay over the first year of their loan?

The aircraft has a maximum capacity of 200 passengers and each flight incurs a fixed cost of $27,000 regardless of the number of passangers. In addition, a cost is also incurred of $75 per passanger to cover such things as catering, booking, baggage handling. (a) (12 marks) The company is thinking of charging $225 per ticket. How many passengers will the airline need on each flight to break even? Find the break-even point algebraically and illustrate it using an EXCEL graph. Attach the printout or copy your EXCEL graph into your assignment submission. Based on your analysis, will Hit-and-Miss realize a profit or a loss if 160 seats are sold for a particular flight? Explain briefly. (b) EXCEL Instructions: make a column called Number of Passengers and in that column enter values from 0 to 200 in increments of 20. Then create two more columns, one for TotalCost and another for TotalRevenue . Enter appropriate formulae in EXCEL to obtain the total cost and total revenue corresponding to each value in the Number of Passengers column. Highlight the resulting three sets of numbers and go to the Chart Wizard to obtain the graph. Make sure that your graph has been labelled appropriately (i.e. title, axis labels, legend). Please refer to Topic 3 in the EXCEL Booklet for further instructions on entering formulae and graphing in EXCEL. (c) (6 marks) Hit-and-Miss Airlines know from previous experience that they are unlikely to sell more than 80 percent of seats on any one flight. Assuming they sell exactly this many, what price per seat should they charge to break even? (d) (6 marks) The company also has the option of accepting a cargo contract. Under this contract, the airline will receive $5,000 per flight for transporting cargo but, because of the extra weight, it will have to reduce its maximum number of passengers to 180.
