  1. Introduction to Mixture Applications Example 1: A jar contains 20 ounces of a solution that is part water and part acid. If the amount of acid is 10% of the total solution, how much acid is in the solution? First, determine what 10% is as a fraction. Recall than percent means per hundred:

  2. 20 ounces total water & acid

  3. 10% acid

  4. The acid is 10% of the total: of the total 20 10%

  5. There are two ounces of acid in the solution. 2 oz.

  6. Review the expression that gave us the amount of acid: of the total 20 20 In decimal form … 10% 10% = (percent acid) × (total amount)

  7. Introduction to Mixture Applications Example 2: A jar contains x ounces of a solution that is part water and part acid. If the amount of acid is 10% of the total solution, how much acid is in the solution?

  8. x ounces total water & acid

  9. 10% acid

  10. The acid is 10% of the total: of the total x 10% = (percent acid) × (total amount)

  11. There are 0.10x ounces of acid in the solution. 0.10x oz. = (percent acid) × (total amount)

  12. Introduction to Mixture Applications Example 3: A jar contains x ounces of a solution that is part water and part acid. If the amount of acid is 65% of the total solution, how much acid is in the solution? Amount acid = (percent acid) × (total amount)
