Serve for 12
1½ cup Pretzels 2 3/4 cups cereals 1 1/8 cup peanuts 1/3 margarine 5/32 cup soy sauce
For 30 people she have to increase it to 30/12 = 15/6 = 2.5
1 ½ x 15/6 → 3/2 x 15/6 → 45/12 → 3 3/4 cup Pretzels
11/4 x 15/6 → 165 / 24 → 6 7/8 cup cereals
1 1/8 x 15/6 = 165 / 48 → 3 7/16 cup peanuts
1/3 x 15/6 = 15/18 → 53/64 magarine
5/32 x 15/6 = 75/192 → 25/64 cup soy sauce
