using the Compound Interest Tables and Interpolation Techniques

(2) Mr. Bud Green, a maintenance manager of a local plant in reviewing the maintenance records of production equipment, has compiled the following maintenance cost data: 5 years ago, $500; 4 years ago, $600; 3 years ago, $700; 2 years ago, $800; and Last year, $900.
