Each morning the manager mixes up 120 pounds of the special blend to sell to his customers.
\n" ); document.write( "The coffee is a mixture of Columbian coffee selling for $5.00 per pound and Brazilian coffee selling for $8.00 per pound.
\n" ); document.write( "The mixture sells for $7.00 per pound.
\n" ); document.write( "How many pounds of Brazilian coffee is in the 120 pound mixture?
\n" ); document.write( "------
\n" ); document.write( "Two equation solution:
\n" ); document.write( "Quantity Eq:::: c + b = 120 lbs.
\n" ); document.write( "Value Eq:::::: 5c +8b = 7*120
\n" ); document.write( "-----------------------------------
\n" ); document.write( "Multiply thru the Quantity equation by 5 to get:
\n" ); document.write( "5c + 5b = 5*120
\n" ); document.write( "---
\n" ); document.write( "Subtract that from the Value Eq and solve for \"b\":
\n" ); document.write( "3b = 2*120
\n" ); document.write( "b = 80 lbs (amount of Brazilian coffee in the mixture)
\n" ); document.write( "==========================================
