The sales S (in thousands of units) of a cleaning solution after x hundred dollars is spent on advertising are given by the following.
\n" ); document.write( "S = 10(1 – e^(kx))
\n" ); document.write( "-----------------------------------
\n" ); document.write( "When $450 is spent on advertising 2600 units are sold. solve for k.
\n" ); document.write( "450 = 10(1-e^(26k)
\n" ); document.write( "----
\n" ); document.write( "45 = 1-e^(26k)
\n" ); document.write( "e^(26k) = -44
\n" ); document.write( "---
\n" ); document.write( "Note: No power of e can result in a negative result.
\n" ); document.write( "So, can't solve for \"k\".
