A delivery van can carry at most 5,000 pounds. If each package weighs 210 pounds on average, what is the maximum number of packages the…

Divide the weight limit by the weight of one package: $\frac{5000}{210} \approx 23.81$. Only whole packages can be loaded, and the van cannot exceed its limit, so round down to 23. Check: 23 packages weigh $23 \times 210 = 4{,}830$ pounds, under the limit, while 24 packages weigh $5{,}040$ pounds, over the limit. That makes choice A correct. Choice B (24) comes from rounding to the nearest or rounding up, and it overloads the van. Choice C (23.8) is not a whole number of packages. Choice D (20) is safe but not the maximum, since three more packages still fit.
