A retail manager is blending two types of gourmet coffee to create a 40-pound house mix. Arrange the following steps in the correct order to set up and solve this mixture problem using the seven-step strategy.

A chef is preparing 50 gallons of a house dressing by mixing balsamic vinegar (costing $5 per gallon) with premium olive oil (costing $8 per gallon). The goal is to create a blend with a total value based on a cost of $6.20 per gallon. If $x$ represents the number of gallons of balsamic vinegar, match each component of the mixture problem setup with its correct algebraic expression or numerical value.

A production manager at a chemical plant is mixing two types of industrial adhesive to create a total of 50 gallons of a specific blend. If $a$ represents the number of gallons of the first adhesive used, which expression correctly represents the number of gallons of the second adhesive needed to complete the batch?

A production manager is mixing two types of industrial resin to create a total of 50 gallons of a specific blend. If $x$ represents the number of gallons of the first resin, the expression used to represent the number of gallons of the second resin is $x - 50$.

Applying the Known-Total Technique in a Mixture Setup

A cost estimator is setting up an algebraic model for a new blended coffee. Instead of using two different variables for the amounts of the two coffee beans, the estimator uses a single variable, $x$, for the first bean and represents the amount of the second bean as the total batch size minus $x$. In our problem-solving strategy, this approach is referred to as the ____ technique.
