    a) $2500 in 5 years when the rate is 6又3/4% compounded annually.

    2500*(1+6.75%)^5=3465.61

    b) $525 in 4 years when the rate is 5又1/2% compounded quarterly

    525*(1+5.5%)^4=650.38

    b) $525 in 4 years when the rate is 5又1/2% compounded quarterly

    525*(1+5.5%/4)^(4*4)=653.21

    是呀5又1/2% compounded quarterly

    則525 × (1+5.5%/4)^16

    計算本利和 = 本金 × (1+利率)^n

    n 為期數

    2. 525 × (1+5.5%)^16 ≒ 1236.5

    quarterly 按季
