Answer:
To calculate Nora's total annual interest on her $800 investment, we can use the following formula:
Interest = Principal x Rate x Time
In this case, the principal is $800, the rate is 6% per annum, and the time is 1 year. Plugging these values into the formula, we get:
Interest = $800 x 0.06 x 1
To convert the 6% rate to a decimal, we divide 6 by 100. This gives us 0.06. We then multiply the principal by the rate and the time to get the total annual interest. So the total annual interest on Nora's $800 investment is:
Interest = $800 x 0.06 x 1 = $48
Therefore, Nora will earn a total of $48 in interest on her $800 investment over the course of one year at a rate of 6% per annum.
