Question

The recipe for iced coffee at starbucks suggests 2 parts milk for every 3 parts coffee. if a venti (the largest size) requires 12 ounces of coffee, how many ounces of milk should be added?

Answer 1

To prepare a Venti-sized Starbucks iced coffee with 12 ounces of coffee, the proportion of 2 parts milk to 3 parts coffee dictates that 8 ounces of milk should be added.

Step-by-step explanation:

The recipe for Starbucks iced coffee suggests a ratio of 2 parts milk to 3 parts coffee. To determine the amount of milk needed for a Venti size that contains 12 ounces of coffee, we use a proportional approach as follows:

Identify the ratio of milk to coffee which is 2:3.

Set up a proportion: Since 3 parts of coffee correspond to 12 ounces, we have (2 milk parts / 3 coffee parts) = (x milk ounces / 12 coffee ounces).

Solve for x, which represents the ounces of milk needed. Thus, x = (2/3) * 12 = 8 ounces.

Therefore, to maintain the correct ratio, you will need to add 8 ounces of milk to 12 ounces of coffee.
