您好,插值法運(yùn)用過(guò)程如下:
r=9%,59/(1+9%)+59/((1+9%)^2)+59/((1+9%)^3)+59/((1+9%)^4)+(59+1250)/((1+9%)^5)-1000=41.90
r=10%,59/(1+10%)+59/((1+10%)^2)+59/((1+10%)^3)+59/((1+10%)^4)+(59+1250)/((1+10%)^5)-1000=-0.19
插值法:
(r-9%)/(10%-9%)=(0-41.90)/(-0.19-41.90)
解方程得出r=9+41.90/(41.90+0.19)=9.9954%≈10%
r=9%,59*3.8897+1250*0.6499=1041.88
r=10%,59*3.7908+1250*0.6209=999.78
插值法:
r=9+(1041.88-1000)/(1041.88-999.78)=9.9948%≈10%
