Young Larry stopped by the corner grocery store and read the following list to the clerk:
10 pounds sugar at $1.25 a pound
4 pounds coffee at $1.50 a pound
2 pounds butter at $1.10 a pound
2 bars soap at $.83 each
"How much does that come to?" asked Larry.
"Twenty-two dollars and thirty-six cents."
"If I gave you three ten dollar bills, how much change would I get?" said the boy.
"Seven dollars and sixty-four cents," stated the clerk who appeared to be irritated by all the questions.
Larry said, as he disappeared through the door, "I don't want to buy the items...that's our arithmetic lesson for tomorrow, and I needed some help with it."
小拉里逛进街角的杂货店，把这么个清单念给店员听：
10磅糖，每磅1.25元
4磅咖啡，每磅1.5元
2磅黄油，每磅1.1元
2条肥皂，每条0.83元
“这总共多少钱啊？”拉里问。
“二十二块三毛六。”
“要是我给你三张十块的钞票，我该拿回多少找头呢？”小男孩又问。
“七块六毛四，”被一连串问题搞烦了的店员说。
“我没想买这些东西……那是我们明天的数学功课，我就想找个帮忙的。”拉里说着话，人就出了店门没影儿了。
