About cash flow question, pls help, thx?

Toy and Fun company is a toy company in Hong Kong. The company produces a
variety of toys for newborn babies and children up to 10 years old. Last year, the
company hired a consultant at a cost of $2200000 to estimate the development of
painting kits. The consulting pointed out that a new launch of painting kits would be
able to stimulate sales of the company. Additional sales revenue of $22400000 per year will be generated by this new product. The expenditure incurred in this new product is listed below:

* If the company accepts this new product, the annual cash expenses of the
company will increase from $84000000 to $86800000.

* The company has to borrow $40000000 from a bank. The bank offers the company
8% interest and additional interest expenses of $3200000 each year.

* Additional inventory of $8400000 will be incurred for the new product.

* The new machine will cost $50400000 with a useful life of four years. The
company applies the simplified straight-line method over the useful life period. This
new machine should be installed before the new project formally starts.

Assume the marginal tax rate is 18% and the required rate of return for the
company is 10%. As the finance manager of the company, you are required to
review this project.

Review and decide whether the following items are relevant cash flows for the
project or not.

A.) i The consulting fee:$2200000
ii The increase in inventory: $8400000
iii Additional interest expense:$3200000 per year.

B.) Develop a capital budgeting analysis to determine whether the company
should accept this project. Remember to show the calculation steps clearly in
order to get full credit.
