Question

An European style café latte uses 1.5oz of espresso and 8oz of milk. You accidentally add 12oz of milk to 1.5oz of espresso. How many oz of espresso should be added to fix this recipe?

Answer 1

To fix the recipe, you need to add 2.25oz of espresso.

Step-by-step explanation:

To fix the recipe, we need to determine the amount of espresso that should be added.

Since the European style café latte recipe calls for 1.5oz of espresso and 8oz of milk, we can find the ratio between the two ingredients: 1.5oz espresso / 8oz milk = 0.1875oz espresso per 1oz milk.

To find the amount of espresso needed to fix the recipe, we can set up a proportion:

0.1875oz espresso / 1oz milk = x / 12oz milk

Cross-multiplying, we get:

0.1875oz espresso * 12oz milk = x

Simplifying, x = 2.25oz espresso.

Answer 2

2.5

Step-by-step explanation:

The one thing that changes in the problem is the milk. It goes from 8 oz. to 12 oz., so we are going to use the oz count to determine the amount of espresso. Since the amount of milk rose, so is the amount of espresso. Now, you take the larger number and divide it by the smaller number (12 / 8 = 1.5). This answer will tell you by what multiple it increased by. Once you have the multiple it increased by, you multiply that answer (1.5) by the other unknown changing number, so 1.5 x 1.5. Do this and you get 2.5.
