1. An owner of a gourmet food store has two varities of herbal tea, one that cost costs $4.00 per kilogram and another that cost $5.00 per kilogram. how many kilograms of each type are needed to make 20 kg of a blend worth $4.60 per kilogram?
\n" ); document.write( ":
\n" ); document.write( "Let x = amt of $5 coffee.
\n" ); document.write( ":
\n" ); document.write( "The total amt is 20 kg, therefore
\n" ); document.write( "(20-x) = amt of 4$ coffee
\n" ); document.write( ":
\n" ); document.write( "5x + 4(20-x) = 4.6(20)
\n" ); document.write( ":
\n" ); document.write( "5x + 80 = - 4x = 92
\n" ); document.write( ":
\n" ); document.write( "5x - 4x = 92 - 80
\n" ); document.write( ":
\n" ); document.write( "x = 12 kg of $5 coffee
\n" ); document.write( ":
\n" ); document.write( "20 - 12 = 8 kg of $4 coffee
\n" ); document.write( ":
\n" ); document.write( ":
\n" ); document.write( "Check:
\n" ); document.write( "5(12) + 4(8) = 4.6(20)
\n" ); document.write( "60 + 32 = 92, confirms our solutions
\n" ); document.write( ":
