A winemaker has two large casks of wine. One wine is $8 \%$ alcohol, and the other is $18 \%$ alcohol. How many liters of cach wine should be mixed to produce 30 liters of wine that $12 \%$ alcohol?

Key Concepts

Mixture Problems

This concept involves combining two or more substances with different characteristics to obtain a mixture with a specified property. It is commonly used in contexts where the final mixture must meet a target concentration or composition, requiring careful calculation of the individual amounts of each component.

Weighted Average

When combining substances with different percentages or concentrations, the overall concentration of the mixture is expressed as a weighted average of the components. The weight corresponds to the amount of each substance, and the final concentration is determined by the ratio of the amounts of the substances in the mixture.

Alligation Method

Alligation is a technique used for solving mixture problems. It provides a straightforward way to determine the ratio in which substances with different concentrations should be mixed to achieve a desired concentration, by comparing the differences between the desired concentration and each component's concentration.

Systems of Equations

This concept involves setting up and solving simultaneous equations based on relationships like total volume and total amount of a specific component in the mixture. In mixture problems, one equation typically represents the sum of the volumes, while another represents the sum of the substance amounts, such as the pure alcohol content.
