Calculate the price of the following bonds, where F is the face value, c is the coupon rate, N is the number of years to maturity, and i is the interest rate (or discount rate, or yield).
1a (e). F = $100, c = 10%, N = 2, i = 8%
1b (e). F = $10,000, c = 6%, N = 3, i = 9%
1c (e). F = $1,000, c = 0%, N = 10, i = 6%
1d (e). F = $10,000, c = 7%, N → ∞ (bond never matures), i = 6%
