Jolene bought three blouses at one price and 2 blouses priced $3 below the others. The total cost was $91.50. Find the prices of the blouses.
\n" ); document.write( ".
\n" ); document.write( "Let x = amount paid for one of the three blouses
\n" ); document.write( "then
\n" ); document.write( "x-3 = amount paid for one of the two blouses
\n" ); document.write( ".
\n" ); document.write( "Our equation:
\n" ); document.write( "3x + 2(x-3) = 91.50
\n" ); document.write( "3x + 2x - 6 = 91.50
\n" ); document.write( "5x - 6 = 91.50
\n" ); document.write( "5x = 97.50
\n" ); document.write( "x = $19.50 (amount for each of set of three)
\n" ); document.write( ".
\n" ); document.write( "then,
\n" ); document.write( "x-3 = 19.5-3 = $16.50 (amount for each of set of two) \n" ); document.write( "

\n" );
