A machine that originally cost $15,600 has a value of $7,500 at the end of 3 years. The same machine has a value of $2,800 at the end of 8 years.
\n" ); document.write( "---
\n" ); document.write( "You have 2 points: (0,15,600) and (3,7500) and (8,2800)\r
\n" ); document.write( "\n" ); document.write( "----
\n" ); document.write( "a. Find the average rate of change in value (depreciation) of the machine between its purchase and the end of 3 years.
\n" ); document.write( "average = (2800-15,600)/(8-0) = -1600
