If \"x\" pounds of regular yogurt, then fat (3%) in this yogurt is \"0.03x\" pounds
\n" ); document.write( "60 pounds of low-fat (1%) yogurt contains \"0.01%2A60=0.6\" pounds of fat.
\n" ); document.write( "If will obtain 60 pounds, when mix x pounds of regular yogurt with no-fat yogurt, then no-fat yogurt is \"%2860-x%29\" pounds. Fat in this yogurt is 0 pounds
\n" ); document.write( "So have equation
\n" ); document.write( "\"0.03x%2B0=0.6\"
\n" ); document.write( "\"x=0.6%2F0.03\"
\n" ); document.write( "\"x=20\" pounds of 3% yogurt
\n" ); document.write( "then no-fat yogurt is \"%2860-x%29=%2860-20%29=40\" pounds
\n" ); document.write( "Answer: 20 pounds of regular yogurt and 40 pounds of no-fat yogurt should be mixed to obtain 60 pounds of low-fat yogurt
