某果品商店进行组合销售。甲种搭配：2千克A水果，4千克B水果：乙种搭配：3克A水果，8千克B水果，1千克C水果：丙种搭配：2千克A水果，6千克B水果，1千克C水果。已知A水果每千克2元，B水果每千克1.2元，C水果每千克10元。某天该商店销售这三种搭配共得441.2元，其中A水果的销售额为116元，问C种水果的销售额为多少元？
解：A水果卖出的数量：116÷2＝58
千克
设甲种搭配卖出x份，乙种搭配卖出y份
那么丙种搭配卖出：(58-2x-3y)/2份
B水果销售额：[4x+8y+6×(58-2x-3y)/2]×1.2=208.8-2.4x-1.2y
C水果销售额：[y+(58-2x-3y)/2]×10=290-10x-5y
根据题意：208.8-2.4x-1.2y+290-10x-5y=441.2-116
12.4x+6.2y=173.6
2x+y=28
C水果的销售额：290-10x-5y=290-5×(2x+y)=150
元
