Final answer:
To find the missing x value for the point (x, 3) that completes the relationship in the ice cream topping recipe, we must set up a proportion based on the given ratio of ingredients and solve it to find that the missing x value is 1.
Step-by-step explanation:
The student is asking to find the missing 'x' value for the point (x, 3) that would fit the proportional relationship between chocolate chips and coconut oil in their recipe for magic shell ice cream topping. The relationship states that for every 1/2 cup of coconut oil, 1 1/2 cups of chocolate chips are needed. Since the point (,3) lies on the line, we can set up a proportion using the known recipe ratio:
1/2 cup coconut oil : 1 1/2 cups chocolate chips = x cups coconut oil : 3 cups chocolate chips
Now, to solve for 'x,' use cross multiplication:
(1/2) * 3 = (1 1/2) * x
1.5 = 1.5 * x
The missing value of 'x' is 1.
