Final answer:
To solve the problem, create a system of equations using the given information and solve for the variables 'm' and 'y'.
Step-by-step explanation:
In order to solve this problem, we can create a system of equations based on the given information. Let's use the variables 'm' for milk, 'y' for yogurt, and 'i' for ice.
Since Robin wants her smoothie to have about 335 calories, we can create the equation: 100m + 190y + 0i = 335
Similarly, since she wants her smoothie to have 24 grams of protein, we can create another equation: 9m + 13y + 0i = 24
Now we can solve the system of equations to find the values of 'm' and 'y' that satisfy both equations.
