Answer:
300 ml of yogurt
Step-by-step explanation:
To find the amount of yogurt Karolina uses in making the salad dressing, we first need to determine the ratio of yogurt to mayonnaise, which is 3:5.
Let the amount of yogurt be 3x and the amount of mayonnaise be 5x, where x is a common factor.
Since the total mixture is 800 ml, the sum of the parts in the ratio is 3x + 5x = 8x = 800 ml.
Now, solve for x:
[tex]8x=800\\x=\frac{800}{8} =100[/tex]
Karolina uses 3 parts of yogurt, which is 3 * 100 = 300 ml of yogurt in making the salad dressing.
