Which part of the passage highlights the main idea?
As a teen, you're beginning to make some grown-up decisions about how to save and spend your money. Learning the right ways to manage money is important. You should set aside at least 10 percent of the money you earn before you are tempted to spend it. These small sums of money will eventually add up to an amount that can help pay for a big purchase in the future. You should also keep track of your spending by creating a budget and documenting your spending habits. Finally, think before your buy something. Many teens buy things on impulse without considering the actual value of those things or the need for the purchase.
