Assuming a 8% interest rate, find the present value of an investment project of $ 10,000 that leads to the following cash flows:

-year 1: $ 0

-years 2-4: $ 700 (each year)

-year 5-7: $ 1,500 (each year)

-year 8: $ 1,000

also, find the year interest rate that gives a net present value of zero.

A withdrawal from an account means taking money out of your account. That means whatever money you have in there becomes a smaller amount because you're subtracting money from the account.

So, to work out how much money Jan withdrew as a negative sum, you just have to look at how much she took out:

-25 - 45 - 75 = -$145

This means Jan took out $145 from her account, and we write it with a negative sign because it's money that's going to be taken away from whatever's in there.

The same thing applies to Julie:

-35 - 55 - 65 = -$155

Julie took out $155 from her account, so her withdrawals were -$155.

Therefore, your final answer for 24a. is -$145 and your answer for 24b. is -$155.
