How many 3-lb cases of bulk potato chips are needed to provide 1½ oz per person to 75 people?

• A. 2
• B. 3
• C. 7
• D. 8

Answer: (B)

Distributing a fixed amount per person requires total volume. Multiply the per-person amount by the number of people: 1.5 oz × 75 = 112.5 oz needed. Each 3-lb case equals 3 × 16 = 48 oz. So the number of cases needed is 112.5 ÷ 48 ≈ 2.34. Since you can’t buy a fraction of a case, you must round up to the next whole case, which is 3 cases. Three cases provide 144 oz, meeting and exceeding the 112.5 oz requirement. If you used only two cases (96 oz), you’d be short by 16.5 oz.
