Steven has 3 pounds of Brand 121 nuts that sell for $2.23 a pound. He also has Brand 330 nuts that sell for $1.75 per pound. If he wants a mixture of nuts that sell for $1.93 a pound, how many pounds of Brand 330 should he add?
\n" ); document.write( "---------------------
\n" ); document.write( "Value equation: 223*3 + 175x = 193(3+x)
\n" ); document.write( "669 + 175x = 579 + 193x
\n" ); document.write( "Subtract 579 from both sides;
\n" ); document.write( "Also, subtract 175x from both sides to get:
\n" ); document.write( "18x = 90
\n" ); document.write( "x = 5 lbs. (amt of Brand 330 nuts needed for the mixture)
\n" ); document.write( "======================
