Alisha is making an 18 - ounce coffee beverage that is made from brewed coffee and milk. The number of ounces of brewed coffee is 5 times greater than the number of ounces of milk. How many ounces of coffee and how many ounces of milk does Alisha need?

The correct answer is that Alisha need 3 ounces of milk and 15 ounces of brewed coffee.

Step-by-step explanation:

Ounces of milk = x

Ounces of brewed coffee = 5x (5 times greater than the number of ounces of milk)

Formula:

x + 5x = 18 (total of ounces of her favorite beverage)

6x = 18

x = 18/6

x = 3

5x = 15

The number of ounces of milk needed by Alisha to make her favorite beverage is 3 and the number of ounces of brewed coffee is 15.
