    Helen got up at seven thirty. Her parents and her little twin brothers went travelling in Australia and she had to take care of herself at home. She opened the fridge, but she found only three pieces of bread in it. She decided to have breakfast in the restaurant at the other side of the street. She sat at a table and the waitress came up to her and said, “Can I take your order, Helen?”

    “But you didn't show your menu to me, Miss White,” said the girl.

    “Oh, sorry! I forget it. Here it is.”

    Helen looked at the menu carefully. It was:

bread  $1.5          egg  $ 0.4

pizza  $2.5          cola  $ 0.3

sandwich $1.5        milk  $ 0.6

hamburger $2.5       coffee  $ 0.9

    Helen took out her purse and found there was only 7 dollars in it.

    “Well,” said White.“What about a hamburger, a pizza, two eggs and a glass of cola?”

    “Oh, no,” said the girl. “I'll buy a storybook this afternoon. It's 2 dollars.”

    “I see,” said the waitress. And then she brought the girl a nice breakfast.
