個問題係咁既
a wealthy benefactor has donated $1,000,000 to establish a perpetuity that will be used to support the operating costs of a local heritage museum to open in three years' time. If the funds earn 4.8% compounded monthly, what monthly payments, the first occurring three years from now, can the museum expect?
已知道正確答案是Pmt=4599.81
但係過程中我輸入了
n=999
i/y=4.8
p/y=1
c/y=12
fv=0
pv=1000000
但係得出來既答案不一,到底哪裡出錯了呢?
