答案

13;18;圈出No。

解析

【分析】
首先明确图中各物品的价格:面包8元,蛋糕15元,苹果5元,果汁3元。第一步计算苹果和面包的总价,用加法运算;第二步计算蛋糕和果汁的总价,同样用加法;第三步计算所有物品的总价格,与15元比较,判断是否能购买所有物品。
【解析】
1. 苹果价格为5元,面包价格为8元,两者总价:$5 + 8 = 13$(元);
2. 蛋糕价格为15元,果汁价格为3元,两者总价:$15 + 3 = 18$(元);
3. 所有物品的总价格:$8 + 15 + 5 + 3 = 31$(元),因为$31 > 15$,所以15元不能买所有物品,选择No。
【答案】
13;18;圈出No
【知识点】
20以内加法、100以内加法、价格计算
【点评】
本题结合生活场景考查加法计算和数的大小比较,需要准确提取物品价格,分步计算后再判断,是基础的数学应用题目。
