exponential rate of decrease
\n" ); document.write( " $\"+c+=+90%2A%28+1+-+.1+%29%5Et+\"$
\n" ); document.write( " $\"+t+\"$ = number of yrs from now
\n" ); document.write( " $\"+c+=+90%2A.9%5E3+\"$
\n" ); document.write( " $\"+c+=+90%2A.729+\"$
\n" ); document.write( " $\"+c+=+65.61+\"$
\n" ); document.write( "In 3 yrs it will cost $65.61
\n" ); document.write( " \n" ); document.write( "
