Remember: Interest is the extra coins a bank garden adds for keeping your coins there. This garden is made up, and your real credits never earn interest.
Read and answer
Read the story first, then answer.
Ana and the Bank GardenAna had saved one hundred pretend coins. She wanted them safe, and she wanted them to grow, so she took them to the Bank Garden, a pretend place made up for this story. A bank keeps coins safe. The garden adds a little extra to coins left there, and that extra is called interest. In this garden, interest was one new coin for every ten coins. After one year the garden added ten coins, so Ana had one hundred ten. In year two the garden held eleven tens, so it added eleven coins, and Ana had one hundred twenty-one. Ana did nothing but wait. The garden is made up, so the numbers are easy. Real banks use different numbers.
