If you have 22 sheep and each consumes 1.5 kg of feed per day, how many 50-lb bags of feed are needed per week?

If you have 22 sheep and each consumes 1.5 kg of feed per day, how many 50-lb bags of feed are needed per week?

• A. 10.2
• B. 15.5
• C. 33.0
• D. 50.8

Answer: (A)

Focus on converting the flock’s daily needs into a weekly bag count. Start with the total daily consumption: 22 sheep × 1.5 kg = 33 kg per day. Over a week (7 days) that becomes 33 kg/day × 7 = 231 kg per week. Convert to pounds: 231 kg × 2.2046 lb/kg ≈ 509 lb. With bags of 50 lb each, the number of bags is 509 lb ÷ 50 lb/bag ≈ 10.18 bags, which rounds to about 10.2 bags per week. In practice you’d buy whole bags, so 11 bags would be needed, but the calculated decimal is 10.2.
