Use the graph showing jamie's account balance to answer the question what is the interest rate on jamie's account? a. 1.9% b. 2.2% c. 18.3% d. 22.5%

Notice, the graph starts off with an account balance of $10, at the 10 over the y-axis, that means the initial amount in the account, or what he initially deposited was 10 bucks.

now... let's use any of the points, say hmm the 2, 10.44.

after 2 years, he's got an extra 44 cents in it, went up to 10.44.

bearing in mind that is a linear graph, and thus is a simple interest rate.
