exactly     equals     item      television    price   husband

  When you buy something and pay for it with bills or coins, you are paying cash. If you don’t have a combination of bills and coins that exactly equals the price of the item, you may give the salesperson too much money. He or she will then give some money back to you. The money you get back is called change. Look at this example.你在購物時如果使用鈔票和硬幣支付，你就是在付現(xiàn)金。如果 你沒有恰好與所購物品價格相等的鈔票和硬幣組合，你可以多給售貨員一些錢。他/她會找給你錢的。你得到的這些返還錢就是找頭。請看下面的例子。

  Your husband is buying a color television set. The total price is $244.90. he gives the salesman $250.00-two hundred-dollar bills and one fifty-dollar bill. The salesman gives him back a five-dollar bill and a dime. Your husband’s change is $5.10.

    你丈夫在買一臺彩色電視機。價格是244.90美元。他給了售貨員250美元——兩張一百美元鈔票和一張五十美元鈔票。售貨員返還給他一張五美元鈔票 和一個一角硬幣。你丈夫得到的找頭是5.10美元。
