Answer 3

I = P x r x t
P is the principal amount, $840.00.
r is the interest rate, 10% per year, or in decimal form, 10/100=0.1.
t is the time involved, 1 month time periods.

Since the interest rate is "per year" and the time interval is 1 month, we need to convert your time interval into "year" as well. Do this by dividing your time, 1- month(s), by 12, since there's 12 months in 1 year.
So, t is 0.0833333....year time periods.
To find the simple interest, we multiply 840 × 0.1 × 0.0833333 to get that the interest is: $7.00.
