Me i want to go to lunch with my family but i can't cause i can't finish this

54+36 = 90
90/6= 15

15 servings

Hello,

We want to find how many ounces of total mixture Barbara has. If she has 54 ounces of granola and 36 ounces of raisins, she has 54 + 36 = 90 ounces of total mixture.

If she has 90 ounces of total mixture, and wants to make 6 ounce servings, we divide the total amount of mixture by the size of the servings.
Doing this, we get
90 / 6 = 15 servings.

She can make 15 servings.

Hope this helps, enjoy your lunch!
