whose recipe uses more potatoes per serving?
jacksons recipe barbaras recipe
how many potatoes would that recipe use to make 16 servings?

Explanation:

Step1: Calculate potatoes per serving for Jackson's recipe

For Jackson's recipe, when servings = 4, potatoes = 3. Potatoes per serving = $\frac{3}{4}= 0.75$

Step2: Calculate potatoes per serving for Barbara's recipe

From the graph, when servings = 5, potatoes = 3. Potatoes per serving = $\frac{3}{5}=0.6$

Step3: Compare the two values

Since $0.75>0.6$, Jackson's recipe uses more potatoes per serving.

Step4: Calculate potatoes for 16 servings in Jackson's recipe

If potatoes per serving is $0.75$, for 16 servings, potatoes = $0.75\times16 = 12$

Answer:

Jackson's recipe uses more potatoes per serving. It would use 12 potatoes for 16 servings.
