You're right for # 2. :-)

It's easiest to use the decimal equivalents for the fractions of a year: 2 1/4 (2.25) and 1 3/4 (1.75).

# 3:

I = 3680 * 0.0675 * 2.25
ReportAnswer #2
The basic formula is Interest equals principal times rate times time or I = PRT.

For # 1:
I = 5432 * 0.062 * 3
I = 1010.35

Follow this pattern. We'll be glad to check your answers.

So for #2 the answer is 1113.75. But I still don't understand #3 and #4 because I don't know how to multiply the years. You know 2 1/4 and 1 3/4
ReportAnswer #4
I have a question, is the different wording of #4 significant? Because it says 5.5% for 1 3/4 years on $2543. I am not having any trouble with the others, just this one.
