Final: The Investment

Part of the Exponentials, Logs & Sequences section of Coddy's Algebra 2 journey. Lesson 48 of 49.

You put 1000 dollars in a savings account that pays 5% interest a year, added at the end of each year. Find the value V of the account after 2 years.

Challenge

1000 dollars is saved at 5% interest a year, added at the end of each year. Find its value V after 2 years. On the blank board, write a V = ... line with the growth rule filled in, then a line with the value as a decimal.
