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. document.getElementById("warp").style.display="none"; document.getElementById("content").style.display="block"; 查看试题解析出处>>
