Robbie is using the recipe below to make chicken noodle soup. he plans to make 6 batches of the soup. he has 2/3 teaspoon of black pepper [chicken noodle soup] 4 cups chicken broth 1 medium carrot, sliced 1 stalk celery, sliced 1/2 cup uncooked egg noodles 1/8 teaspoon ground black pepper 1 cup shredded cook chicken part a: write an expression that robie can use to determine how much black pepper is needed for 6 batches. part b: draw a model to show how robbie can find the product from part a (don't say how to draw the model just say how to solve the expression in part a.) part c: does robbie have enough black pepper for 6 batches of the soup? explain your reasoning. (< explain.)

Part A: Write an expression that Robie can use to determine how much black pepper is needed for 6 batches.
 The first thing you should know in this case is the amount of pepper available and the amount of black pepper in each batches.
 Available = s 2/3 teaspoon
 Batches = 1/8 teaspoon
 Let
 x = number of batches:
 y = black pepper
 The expression is then:
 y = 1/8x
 0 <= x <= 6
 ---
 Part B: Draw a Model to show how Robbie can find the product from Part A (do not say how to draw the model just say how to solve the expression in Part A.)
 You must graph the line of part A:
 y = 1/8x
 Then, check for x = 6 the value of y to know how much black pepper is needed for 6 batches.
 
 Part C: Does Robbie have enough black pepper for 6 batches of the soup? Explain your reasoning. (<--- PLEASE EXPLAIN.) 
 Substituting x = 6
 y = 1/8 (6)
 y = 6/8
 y = 3/4
 3/4> 2/3
 Robbie has not enough black pepper for 6 batches of the soup

No, the ratios are not equivalent to 2/3. To create an equivalent ratio, you need to multiply both numbers in the original ratio by the same number.

I took a test and it said that this was correct. I hope this helps!
