Question

Bob has a recipe for salad dressing the recipe says to mix 1/4 cup lemon juice. 1/8 cup mustard and 1/4 cup vinegar how much lemon juice does he need to make 4 cups of salad dressing show your work

Answer 1

Explanation:

1/4*x + 1/8*x + 1/4 * x = 4 cups

5/8 * x = 4 cups Multiply both sides by 8/5

5/8 * 8/5 x = 4 8/5

x = 32/5

x = 6.4

That means that each ingredient must be multiplied by 6.4

1/4 * 6.4 = 1.6 cups lemon juice

1/8 * 6.4 = .8 cups mustard

1/4 * 6.4 = 1.6 cups vinegar

Total = 4 cups.
