These problems solved using the future value of an annuity due formula by calculating the sum of a series payment at the beginning period through a specific amount of time. The formula of the future value of an annuity due is FV = C*(((1+i)^n - 1)/i)*(1+i), where FV is the future value, C is the payment for each period, n is the period of time, and i is the interest rate. Calculation for Question 1: FV = $1,000*(((1+6%)^(5)-1)/6%)*(1+6%) and calculation for Question 2: FV = $1,000*(((1+1%)^(2)-1)/1%)*(1+1%)
