These are estimation problems so they should not be worked with a paper and pencil or with a calculator. For example, with Problem 5 , the interest rate is not stated, but you should still recognize a reasonable answer. Let's see, $100 @ 5% for 1 year is $5, so the future value seems to be $100 + $5 = $105.
