Question

Dana received good news from her parents with the increase of her school allowance, so she spends more money on pretzels every week. How can you explain this with a graph?

This is an example of a shift in Dana's demand curve. She has a permanent increase in her income, so she begins to buy more, even though the prices haven't dropped.
