Question

if you need 17oz for 12 servings, how many oz would you need for 15 serving?

Answer 1

Jw, this is the solution:

We will use Direct Rule as follows:

Ounces Servings

72 12

x 15

________________

12 * x = 72 * 15

12x = 1,080

Dividing by 12 at both sides:

12x/12 = 1,080/12

x = 90

We would need 90 ounces for 15 servings
