Compound appreciation and depreciation (Part 2)

Maths

Growth and decay

If an investment of $500.00 increases by 13% per year for 6 years, the amount it would be at the end of the 6 years would be...

£100.00 decreases by 5% in one year, followed by an increase of 5% in the next year, and then decreases again by 2% for 8 years. What would the final amount be?

If a teddy bear depreciates from £3.00 by 18% per year for 5 years, what is the final value of the teddy bear?

In order to decrease an amount by 19% for 2 years, I would need to multiply the amount by 0.19^2

In order to increase an amount by 7.5% for 3 years, I would need to multiply the amount by 1.075^3

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).
