问题 At the wholesale store you can buy an 8-pack of hot dogs for $1.55, a 20-pack for $3.05, and a 250-pack for $22.95. What is the greatest number of hot dogs you can buy at this store with $200?
选项 A、1,108
B、2,100
C、2,108
D、2,124
E、2,256
答案 B
解析 You should start with the 250-packs, because that is the best value, with each hot dog costing less than 10 cents. Rounding 22.95 to 23 for simplicity, you can determine that you can afford 8 of the 250-packs, for a total of $183.60. The 20-packs are the next best value at around 15 cents per hot dog, so with the remaining $16.40 you can buy 5 of the 20-packs for $15.25, leaving $1.15. $1.15 isn’t enough for an 8-pack, so the total number of hot dogs is 8×250+5×20=2,100.
