The price of the latest incredible iThing from Apple starts at $200 when it is first released. Every year it gets better but the price goes up 8%. What is the price after 20 years?
A swimming pool is 50 feet by 150 feet. It is surrounded by a three foot wide deck. Find the area of the deck in square feet.
The price goes up 8% a year so thats 0.08. The original price is $200.
200*(1+0.08)^20
The price will be about $932. (incredible iThing answer)
Find the whole area of the swimming pool plus the deck and then subtract the area of the swimming pool.
(50+3)(150+3)=8109.
8109-(50)(150)=609 ft^2 (Answer for pool deck area)
