Sarah takes out a $38,876 loan for college. It has a 6.6% interest rate and compounds annually. The loan interest doesn’t start until after she graduates.
When she graduates, Sarah only makes enough money to pay for her basic necessities (food, transit, home). So, she can’t immediately start making loan payments. She sets a goal of making a large payment on her loan after saving up for 11 years. 
a) How much will she owe after 11 years? Use the sketch tool to show your work.
