Consider a large country that imports good R. Some of the total quantity of R domestically consumed is supplied by domestic producers and the rest of it is imported. Then suppose that the government imposed a tariff on each unit of R that is imported, so that the quantity of R imported is somewhat reduced. Draw a demand and supply diagram that shows the effect of the tariff. On your diagram, 4 of 4 shade-in the area that represents the government revenue from the tariff which is in effect being paid by foreign exporters (please do not shade-in any other areas). Then provide an explanation for why this area represents the government revenue from the tariff which is in effect being paid by foreign exporters. (10 Marks, maximum word limit: 100 words

Here are the net cash flows for a project your company is considering:
Year 0 = -1000

Year 1 = 250

Year 2 = 449

Year 3 = 800

Year 4 = 500

Year 5 = 500
If the payback period with interest is 3 years, for what range of interest rates is this project worth doing (start your analysis with an interest rate of 0%)?

** Kindly just don’t directly draw the table with values in it, it’ll be helpful to include explanation of how you get to fill the table . Already I posted this question earlier and noticed that someone had just randomly written someone else’s who has solved the question with no change in word format too.
