Compound appreciation and depreciation (Part 1)

Maths

Growth and decay

Decreasing £100 by 5% for 8 years would give a final balance of...

If I deposited £500 in a bank account and left it there for 6 years at a rate of 4% compound interest, how much would I have at the end of the 6 years?

If an antique was originally bought for £55 and grew by 6.5% per year for 7 years, then the value at the end of 7 years would be £85.46 (to the nearest penny).

If 53 increased by 23% for 'n' number of years, which of the following would provide a general formula to work out how much it had grown to?

If an antique grew 6.5% a year for 7 years from the purchase price of £55, it would be worth £85.46 (to the nearest penny).

What would the value of £300 become if it grew by 5% and then another 5%?

If an antique appreciates by 6% per year for 11 years, the decimal multiplier would be 1.06^11.

If I want to find the 'original' price of something that is currently in a sale and has 40%, I always need to find 100% of the amount to work out the original price.

If I start with a number, increase it by 30% and then decrease it by 30%, I get back to the original number.

The decimal multiplier to increase an amount by 6% for 5 years would be...
