Kelly has a coffee shop. Tea is $1.05, Coffee is $1.35, and Hot Chocolate is $2.25.\r
\n" ); document.write( "\n" ); document.write( "One day she sold 20 more cups of coffee than hot chocolate, 30 more cups of coffee than tea for a total of $202.50. \r
\n" ); document.write( "\n" ); document.write( "How many cups of each drink did she sell?
\n" ); document.write( "------------------------
\n" ); document.write( "Let # of hot chocolate be \"h\".
\n" ); document.write( "Then # of coffee sold was \"h+20\"
\n" ); document.write( "And # of tea sold was h+20-30 = \"h-10\"
\n" ); document.write( "------------------------
\n" ); document.write( "Value Equation:
\n" ); document.write( "2.25h + 1.35(h+20) + 1.05(h-10) = 202.50
\n" ); document.write( "Multiply thru by 100 to get:
\n" ); document.write( "225h + 135h + 2700 + 105h - 1050 = 20250
\n" ); document.write( "---
\n" ); document.write( "h = 40 (# of cups of hot chocolate sold)
\n" ); document.write( "h+20 = 60 (# of cups of coffee sold)
\n" ); document.write( "h-10 = 30 (# of cups of tea sold)
\n" ); document.write( "======================================
