Here are the answers to choose from:
A. Butter: 13.9%, Sugar: 20.3%, Flour: 41.8%, Milk: 23.9% *****
B. Butter: 23.9%, sugar: 20.3%, Flour: 51.8%, Milk: 23.9%
C. Butter: 13.9%, Sugar: 20.3%, Flour; 11.8%, Milk: 53.9%
D. Butter: 33.9%, Sugar: 20.3%, Flour: 41.8%, Milk: 23.9%

total ounces = 32 + 48 + 96 + 54 = 230
32 oz butter / 230 = .1391 * 100% rounded to the nearest tenth = 13.9%
48 oz sugar / 230 = .2086 * 100% rounded to the nearest tenth = 20.9%
96 oz flour / 230 = .4173 * 100% rounded to the nearest tenth = 41.7%
54 oz milk / 230 = .2347 * 100% rounded to the nearest tenth = 23.5%
-----
13.9% + 20.9% + 41.7% + 23.5% = 100% as it should.
-----
the percentages shown in the answer selections do not all agree with my calculations. i show 20.9% for sugar and they show 20.3%. i show 23.5% for milk and they show 23.9%. i show 41.7% for flour and they show 41.8%. the only one we actually agree on is butter.
-----
selection A, however, is the closest to the true answer so I chose that.
