  1. Introduction to Mixture Applications The following is designed to help you understand the basics of one of the popular application problems in introductory algebra: mixture problems. Example 1: Recall that percent means per hundred, so ...

  2. Example 2: The jar on the right is marked in 10 equal divisions. 10 9 8 7 6 5 4 3 2 1 Fill the jar with acid up to the “2” mark …

  3. Example 2: The jar on the right is marked in 10 equal divisions. 10 9 8 7 6 5 4 3 2 1 Fill the jar with acid up to the “2” mark … … and add water to the top of the glass…

  4. Example 2: The jar on the right is marked in 10 equal divisions. 10 9 8 7 6 5 4 3 2 1 Fill the jar with acid up to the “2” mark … … and add water to the top of the glass…

  5. 10 9 8 7 6 5 4 3 2 1 … and 8 units of water. The jar has 2 units of acid …

  6. 10 9 8 7 6 5 4 3 2 1 … for a total of 10 units of mixed solution.

  7. 10 9 8 7 6 5 4 3 2 1 The acid represents 2 units … … out of a total of 10 units, or …

  8. 10 9 8 7 6 5 4 3 2 1

  9. This means that the acid represents 20% of the total liquid in the jar. 10 9 8 7 6 5 4 3 2 1 Figured another way, the amount of acid is

  10. Example 3: Mix 2 unitsof acid with only 6 units of added water. 10 9 8 7 6 5 4 3 2 1

  11. Example 3: Mix 2 unitsof acid with only 6 units of added water. 10 9 8 7 6 5 4 3 2 1 6 units of water 2 units of acid

  12. 10 9 8 7 6 5 4 3 2 1

  13. This means that the acid represents 25% of the total liquid in the jar. 10 9 8 7 6 5 4 3 2 1 Figured another way, the amount of acid is

  14. Example 4: Mix acid and water again. 10 9 8 7 6 5 4 3 2 1

  15. Example 4: Mix acid and water again. 10 9 8 7 6 5 4 3 2 1

  16. 10 9 8 7 6 5 4 3 2 1

  17. Example 5: Mix acid and water again. 10 9 8 7 6 5 4 3 2 1

  18. Example 5: Mix acid and water again. 10 9 8 7 6 5 4 3 2 1 If the solution is 60% acid, determine the number of units of acid

  19. 10 9 8 7 6 5 4 3 2 1

  20. Example 6: Assume the jar has x units of solution that is 40% acid. 10 9 8 7 6 5 4 3 2 1 Write an expression for the amount of acid in the jar.
