我花了整整一夜为我的课程编写这段代码，它已经完成了，但我的输出值（com2）之一应该是0.10美元，我完全不知道为什么。
我要粘贴整个程序，如果您有任何建议请告诉我！ ：）
目标结果：
Salesperson: GARY
Tier: B
Base Salary: $ 800.89
Commission 1: $ 1200.00
Commission 2: $ 152.28
Total Commission: $ 1352.28
Monthly Salary: $ 2153.17
我目前的成果：
Salesperson: GARY
Tier: B
Base Salary: $ 800.89
Commission 1: $ 1200.00
Commission 2: $ 152.18
Total Commision: $ 1352.18
Monthly Salary: $ 2153.07

答案 0 :(得分：0)
佣金2：152.18美元是正确的。 检查代码：
com2 = (((totalSales - 10500) * 0.03) + 125);
答案 1 :(得分：0)
对于double pCost = 950.50;的12次溢价销售，您得到的totalSum为11406.这意味着您对com2使用以下计算：
if (totalSales >= 10500 && totalSales < 13500)
com2 = (((totalSales - 10500) * 0.03) + 125);
评估结果为152.18。
现在totalSales必须得到什么才能产生152.28？
(152.28 - 125)/0.03 + 10500 = 27.28/0.03 + 10500
= 909,3333333333 + 10500
= 11.409,33333333333
因此，一台笔记本电脑的价格为11.409,33333333333/12，而且永远无法评估为正确的货币价值。因此，如果您正确设置了变量，则152.28可能无法获得正确的结果。
因此，我会得出结论：输入和输出的组合是错误的，或者某些参数设置不正确。我的猜测是它在GOAL部分是一个拼写错误，而com2应该是你152.18的结果。
