A coffee distributor needs to mix a(n) Rift Valley coffee blend that normally sells for $10.00 per pound with a Breakfast coffee blend that normally sells for $14.30 per pound to create 20 pounds of a coffee that can sell for $12.58 per pound.
\n" ); document.write( " How many pounds of each kind of coffee should they mix?
\n" ); document.write( ":
\n" ); document.write( "let x = amt of $14.30 coffee required
\n" ); document.write( "the total result is to be 20 lb, therefore
\n" ); document.write( "(20-x) = amt of $10 coffee required
\n" ); document.write( ":
\n" ); document.write( "14.30x + 10(20-x) = 12.58(20)
\n" ); document.write( "14.30x + 200 - 10x = 251.6
\n" ); document.write( "14.30x - 10x = 251.6 - 200
\n" ); document.write( "4.30x = 51.6
\n" ); document.write( "x = 51.6/4.30
\n" ); document.write( "x = 12 lb of $14.30 coffee required
\n" ); document.write( "I'll let you find the amt of $10 coffee required \n" ); document.write( "
