4. Suppose, Jessica mixes x pounds of cinnamon glaze to 10 pounds of sugar.

Price of sugar is $0.43 per pound.
Price of cinnamon glaze (25% more than that of sugar) is 1.25 x $0.43 = $0.5375 per pound.

Thus total cost of (10+x) pounds of the mixture is $(4.3+0.5375x).

The cost of the mixture is $0.5 per pound. This implies,

In the mixture 56/3 pounds of cinnamon glaze is added to 10 pounds of sugar.

So, the content of sugar in the mixture is = 35%.
