7. Your aunt gave you a $400 bond. If the bond earns 8% interest per annum compounded annually, what will the bond be worth in 3 years? A = P(1 + i) n A = P = i = n = The bond will be worth in 3 years. Find the value of the bond if the interest is calculated quarterly. A = P(1 + i) n A = P = i = n = The bond will be worth in 3 years. 2.7 Compound Interest
