4. Suppose, Jessica mixes x pounds of cinnamon glaze to 10 pounds of sugar.\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "Price of sugar is $0.43 per pound.
\n" ); document.write( "Price of cinnamon glaze (25% more than that of sugar) is 1.25 x $0.43 = $0.5375 per pound.\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "Thus total cost of (10+x) pounds of the mixture is $(4.3+0.5375x).\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "The cost of the mixture is $0.5 per pound. This implies,
\n" ); document.write( "\"%284.3%2B0.5375x%29%2F%2810%2Bx%29=0.5\"
\n" ); document.write( "\"4.3%2B0.5375x=0.5%2810%2Bx%29\"
\n" ); document.write( "\"4.3%2B0.5375x=5%2B0.5x\"
\n" ); document.write( "\"0.0375x=0.7\"
\n" ); document.write( "\"x=56%2F3\"\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "In the mixture 56/3 pounds of cinnamon glaze is added to 10 pounds of sugar.\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "So, the content of sugar in the mixture is \"10%2F%2810%2B56%2F3%29=+0.35\" = 35%.
\n" ); document.write( "
