\n" ); document.write( " if they sold all 90 pieces and took in $705 find how many pieces they sold at the original price and how many pieces they sold at the reduced price?
\n" ); document.write( ":
\n" ); document.write( "let n = number sold at original price
\n" ); document.write( "then
\n" ); document.write( "(90-n) = number sold at reduced price
\n" ); document.write( ":
\n" ); document.write( "9.50n + 7.50(90-n) = 705
\n" ); document.write( "9.50n + 675 - 7.50n = 705
\n" ); document.write( "9.5n - 7.5n = 705 - 675
\n" ); document.write( "2n = 30
\n" ); document.write( "n = 15 units at the original price
\n" ); document.write( "then
\n" ); document.write( "90-15 = 75 units at the reduced price
