The only GSM8K problem that most frontier models get wrong.
Prompt
A landscaping company is delivering flagstones to a customer’s yard. Each flagstone weighs 75 pounds. If the delivery trucks can carry a total weight of 2000 pounds, how many trucks will be needed to transport 80 flagstones in one trip?
Answer guidance
Each truck can only hold 26 flagstones: 26*75=1950. Since 26*3 = 78, all 80 cannot fit on 3 trucks. So, 4 trucks are needed.
