  澳际培训提醒各位参加准备sat考试的同学,仔细看完以上的sat考试官网题目,然后再看下面的SAT题目答案更有效哦。

  答案:C

  解析:

  Choice C is correct. Tony's first goal is that his total fundraiser sales from 15-dollar boxes of candy and 20-dollar t-shirts will be more than $300. Tony's fundraiser sales can be calculated by (price per T-shirt)*(number of T-shirts sold) + (price per box of candy)*(number of boxes of candy sold). If Tony meets this goal, this value will be greater than $300. This situation can be expressed with the following inequality: 15c+20t>300.

  Tony's second goal is that he will sell at least as many T-shirts as boxes of candy. Therore, the second inequality should show that the number T-shirts sold, t, is greater than or equal to the number of boxes of candy sold, c. This situation can be expressed with the following inequality: t≥c.

  Therore, the following system of inequalities best models the situation: 15c+20t≤300 t≥c.
