例题：An online store receives customer satisfaction ratings between 0 – 100, inclusive. In the first 10 ratings the store received, the average (arithmetic mean) of the ratings was 75. What is the least value the store can receive for the 11th rating and still be able to have an average of at least 85 for the first 20 ratings.
题目主要意思为：一家在线商店会收到评分为0-100分之间的顾客满意度评价，收到的前10个评价得分平均为75，如果要保证前20个评价的平均得分为85，商店收到的第11个评价的最少为多少分?
大家可以发现题目非常贴近我们的生活，在网购如此发达的中国，相信大家作为买家都给过店家评价吧。在这道题中，商店需要计算好评率。这类题我们都可以看做“应用题”，解答应用题首先需要将题目给出的情境抽象化：在0-100中先按顺序选择10个数，他们的平均数为75，如果再依次选择10个数，为了保证这20个数的平均数为85，第11个数最少应该是几?然后再根据我们已经掌握的相关知识点解题即可。
另外需要注意的是新SAT数学题目的内容和形式更加多样化：与实际生活、工作相结合。这要求考生们在平时备考中积累与留心更多社会常识与经验。
