Then to discount money in the future to the present, we divide it by 1 plus the discount rate so this is a 5 discount rate.

Do you have a student fare?

Well, that was x.

Another way to kind of just talk about this is to get the present value of 110 a year from now, we discount the value by a discount rate.

Are there special evening rates?

So x minus twenty five percent x is equal to the sale price.

Well the antiderivative of y squared and you have to divide by 3, so it's y cubed over 6.

The probability of reaching S prime given that we started state S and apply action A.

Are there any discount tickets for me?

35 divided by and it's 2 years out, so we discount by our discount rate twice so it's divided by 1.05 squared.

In this example that I did in the previous video, it was the pre tax return on asset.

Then we get the Q value of 100 minus the Q value of zero, and the discount rate is 90.

And this one that was in Kenya, they went around and distributed to people vouchers, discount vouchers.

So I'm going to basically follow what we did in lecture.

These are 30 percent off.

So this is 8t squared plus I'm just dividing both sides of this equation by 2.

Discount rate

Now what can we do ?

I had two earlier in England.

when the sale has a certain percentage ?

Roughly, what this operator does is it halves a number.

What the click with left mouse button should do.

What the click with middle mouse button should do.

I'll be taking team members from each division and creating a new team.

If there's a 10 dollar product, we can put that 10 dollar product in here for x, and then we would say 0.30 times 10.

60 off.

To compound the amount of money we invest we multiply the amount we invest times 1 plus the yield.

So 2009 money, that's worth 1.

I'll say p, just so it makes sense, p is equal to the percentage off.

We could have said Let y equal the discount

And we didn't have to use these words and these letters.

And it just depended on how the mathematics work out.

And there are other videos that go into far more depth on the intuition behind that.

Let's say in every year it's going to make 1.

That's really important for now, just for this one quiz.

And they say that the new customer gets a one time discount of 3.

So len(data) as we know gives me the number of elements.

And this discount rate, this is where all of the fudge factor occurs in finance.

In return on equity, the numerator is the net income that we got, so it's 350,000.

So let's divide both the numerator and the denominator by 7.

So let's say you did it with 4.

Plus 1 is 33. 62 00 03 16,95 gt 00 03 20,75 And now we divide this number by 4.

Well, 4 times 84, we already said, is 336.
