Question

A recipe for tuna casserole that calls for 10 ounces of cream of chicken soup for every 3 cups of elbow-shaped pasta.

Draw a double number line diagram that represents the amounts of soup and pasta in different-sized batches of this recipe.


If you made a large amount of tuna casserole by mixing 40 ounces of soup with 15 cups of pasta, would it taste the same as the original recipe? Explain or show your reasoning.

The original recipe called for 6 ounces of tuna for every 3 cups of pasta. Add a line to your diagram to represent the amount of tuna in different batches of casserole.

How many ounces of soup should you mix with 30 ounces of tuna to make a casserole that tastes the same as the original recipe?

Answer 1

Hi there um I think the answer to the first part of the question is the cups of pasta would be the same as original recipe but the soup is a bit over it should be 30 not 40. But the pasta is correct because original recipe has 3 cups of pasta and this large amount one have 15 cups with is 3 x 5 = 15. I think u understand it is a bit confusing but I hope I helped
