NPV & IRR: Formula + TI BA II Plus + Excel – Equipment Purchase & Residual value
Calculating the NPV and IRR: A piece of equipment purchased today for $20,000 can generate the following cash flows over 4 years:
Year 1: $5,500
Year 2: $7,000
Year 3: $8,000
Year 4: $4,500
At the end of Year 4, the equipment can be sold for $3,500. Assume an 8% required rate of return.

Thank you so much! I was struggling until I saw this video. Easy to follow!
You're welcome, Nikki.
Thanks🎉
Explained like a Lion🦁
How did it become -13 = - 20 and how did it become Y= 1.54??
Excellent presentation clearly explaining integer LP. Thanks a lot.
You're welcome, Alan.
thank you so much for being so straightforward
if i have my calculator programmed would the inverse of my final maximization problem = the minimum?
If your calculator is set to Maximize, and you want to Minimize, you can simply multiply the objective function by -1, then Maximize. After obtaining the objective function value (no the optimal solution point), you will then need to multiply it by -1.
Well explained ❤
Thanks, Peter 🙏
finally made sense to me
Glad it helps. Thanks for dropping a note.
Thank you Sir. Appreciate your video!

Not good explainations
When n is greater than 30 ain’t you supposed to use z table???
Some texts use Z when n > 30, and some don't. If your course says use Z, then do it.
will they give you the standard normal table or you will solve for it?
Normally you're given the table. Otherwise, you can use software to obtain the values.
Very effective and clear!!! You are a wonderful teacher!!👍
Thank you!
Thank you very much
Wow thank you so much this was so helpful

"peace care Hospital would like to use the EOQ model" to find what?
thanks
the formula in cell e2 gives error message on my excel. There is no mistake in what we do but it just does not work
Make the cells are either empty or contain only numbers, then try this pasting this: =SUMPRODUCT(B3:D3,B2:D2)
How can we find cost of capital if not provided in the question?
Bro, Predecessor is missing help guide, what are you doing

Explain Why it is a TWO TAIL (0.025) and not One Tail (0.05). Much appreciated
By default a 95% confidence level is located in the middle of the distribution, leaving 0.05 area which is divided equally (.025) into the two tails.
@@joshemmanif i could rephrase, there are a few questions i’ve seen where one tail (a) is used instead of (a/2) such as a below or above average comparison. Could you explain when that is used?
@@JAG_158 See if this helps: ua-cam.com/video/Iv1RQnjV-1U/v-deo.html
Omg thank you so much 🫶🏽. I’ve trying to solve this particular question for sometime now
Does this mean the critical path is the same as the finish
@@itstaiba3005 As stated at 6:46, the critical is the path: B-D-E-F. The finish time however is 32 weeks.
@@joshemman yes, but I was told if the total for your critical path is not the same as your finish time then it’s wrong. In this case the finish time is 32 and the total for critical path is also 32
@@itstaiba3005 that's correct!
@@joshemman alright. Thank you, I appreciate it
Thanks for your Help Joshua <3!😎
