Check list:

  1. Use simple and compound decay formulae \(A = P\left( {1 - in} \right)\) and \(A = P{\left( {1 - i} \right)^n}\) to solve problems (including straight line depreciation on a reducing balance).
  2. The effect of different periods of compound growth and decay, including nominal and effective interest rates.
