Math Help  Compound Interest  Accumulated Amount  Car Race Theme  Game Tips:  The compound amount A , can be calculated using the formula A = P(1+i)^{n} where P is the principal amount invested (Example: $200.) i is the interest rate per conversion period (Example: 4% = .04) n is the number of conversion periods (Example: 5 years).  Example 1: The compound amount that results from investing $200 for 5 years at the interest rate of 4% compounded annually is calculated as A = 200(1+.04)^{5}. The expression A = 200(1.04)^{5} can be evaluated using a calculator to get A = 243.33 dollars. The calculator should have a button to do exponents. (Sample buttons: x^{y} , a^{x} , y^{x} etc.)  Example 2: The compound amount that results from investing $200 for 5 years at the interest rate of 4% compounded quarterly is calculated as A = 200(1+.01)^{20}. The expression A = 200(1.01)^{20} can be evaluated using a calculator to get A = 244.04 dollars. Interest rates (such as 4%) are quoted per annum unless otherwise stated.  The game can be played using the mouse by itself or using the keyboard by itself.  If the game doesn't respond to keyboard input, click inside the game area to reset the game's focus.  Adjust the game's speed by pressing the + or  key repeatedly.
