How much interest will Charlie's initial investment eam over the 15-year period?
How much money does Charlie have after the 15 years?

Interest: $390 | Total: $715

Step-by-step explanation:

To answer the first question, we can use the simple interest formula provided:

P = initial balance

r = annual interest rate

t = time

First, change 8% into the decimal form:

8% -> -> 0.08

Now, plug in the values:

Charlie made $390 of interest. To find the total, just add that number to $325.

Charlie's total money made was $715.
