A food manufacturer has created four prototypes of a new product to be launched next year. Each prototype contains three main ingredients—fruit, wheat flour, and chocolate—in varying proportions, as shown in the first graph. The cost per pound (Price/lb) for each ingredient is shown in the second graph.
From each drop-down menu, select the option that creates the most accurate statement according to the information provided.

Official Solution:
Looking at the second chart, we see that Wheat is the cheapest ingredient, while Chocolate is the most expensive. Since all products weigh the same, it’s reasonable to assume that the cheapest product will be the one that uses the highest percentage of Wheat and the lowest percentage of Chocolate. This is our initial assumption going into the question.
From the first graph, we can identify that Prototype C fits this pattern—it contains 50% Wheat and only 10% Chocolate, making it the likely cheapest product. There’s no need to calculate the exact cost to determine the answer or compare the other prototypes.
For the second dropdown, however, we do need the exact cost of the cheapest product.
Calculating the cost for Prototype C, we get: 0.4 * 20 + 0.5 * 10 + 0.1 * 40 = 17.
Correct answer:
Dropdown 1: "Prototype C"
Dropdown 2: "17"

Hey, Shouldnt the answer for dropdown 1 be 'protoype D'? as that one represent the composition of "0.4x20 + 0.5x10 + 0.1x40 = 17"
