Think of price as a kind of concentration. The candies and the mixtures of candies have DOLLARS dissolved or dispersed within them.

Assign ONE variable to the quantity of either of the candies.
Example to start, let x be the quantity of the 0.90 dollar per pound candy; then 100-x is the quantity of the 1.30 dollar per pound candy.

Study what this lesson example shows, because the process would work the same way.
