7) The Shell Corp. owns a piece of petroleum drilling equipment that costs $100,000 and will be depreciated by MACRS depreciation with B=$100,000, N=5 years, S=$0. There is a combined 50% tax rate. Shell will lease the equipment to others each year and receive $50,000 per year. At the end of 2 years, the firm will sell the equipment for $50,000. If the firm requires a 10% after-tax rate of return, what is the PW of the investment?

I am confused on #36 of 3.3 in Finite Math for Business.  My teacher wants me to find the interest using the TVM solver on my TI-84 and using the formula I=PRT.  I am not sure what values to plug into my calculator though.

Question 3 Listen What are the values of r and r² for the below table of data? Hint: Make sure your diagnostics are turned on. Enter the data into L1 and L2. Click STAT, CALC, and choose option 8: Lin Reg(a+bx). A r = -0.862 r2=0.743 B r=0.673 2=0.820 X y 5 C r=0.743 r2=-0.862 8 22 23.9 14 9 14 17 20 5.2

Further info is in the attached images For the Excel part of the question give the solutions in the form of the Excel equations. Please and thank you! :) Download the Applying Excel form and enter formulas in all cells that contain question marks. For example, in cell B34 enter the formula "= B9". After entering formulas in all of the cells that contained question marks, verify that the dollar amounts match the example in the text. Check your worksheet by changing the beginning work in process inventory to 100 units, the units started into production during the period to 2,500 units, and the units in ending work in process inventory to 200 units, keeping all of the other data the same as in the original example. If your worksheet is operating properly, the cost per equivalent unit for materials should now be $152.50 and the cost per equivalent unit for conversion should be $145.50. Thank you!

Please solve in Excel with explanation computation for each steps answer in text form

can you do it again, please, no tables, only formulas, please
