I’m going to put $100,000 into an investment at the beginning of year 1. At the end of year 2, I am going to add $55,000 more to the investment. In year 4, I will start to remove $20,000 per year (on the first day of the year). If the interest rate on the investment is 8.2%/year compounded annually, how long (to the nearest year) before the balance in the investment drops to zero? Work this problem on a spreadsheet using simple and compound interest formulas only.

  19 years

Step-by-step explanation:

The attached spreadsheet shows the balance will be zero at the beginning of year 19, when the last $10,423.27 is withdrawn from the account.

__

One could argue that the "nearest year" is year 18, when the balance after the withdrawal is less than $10,000.

_____

In the attached spreadsheet, the ending balance is 1.082 times the beginning balance (after deposits and withdrawals), which is the ending balance of the year before (after deposits).

In year 1 the beginning balance has 100,000 added. In year 2, the ending balance has 55,000 added. In year 4 and every year after, the beginning balance as 20,000 subtracted.

the answer would be d

straight away you can eliminate a and c because not all books contain a scientific skill because some may be fiction. c is also wrong because it saids that the only way children can learn is through books which is incorrect.

b is also wrong because reading can be a scientific skill but not always, therefore it is wrong which leaves you with d, the correct answer since it said that it can children learn.

hope this ! : 3
