Work: Calculate the value of equation (1*(1000*3.5%)/(1+4%)+2*1*(1000*3.5%)/(1+4%)^2+3*1*(1000*3.5%)/(1+4%)^3+4*1*(1000*3.5%)/(1+4%)^4)/981.85 .
Question type: Mathematical calculation
Solution:
(1*(1000*3.5%)/(1+4%)+2*1*(1000*3.5%)/(1+4%)^2+3*1*(1000*3.5%)/(1+4%)^3+4*1*(1000*3.5%)/(1+4%)^4)/981.85
=(1*35/(1+4%)+2*1*(1000*3.5%)/(1+4%)^2+3*1*(1000*3.5%)/(1+4%)^3+4*1*(1000*3.5%)/(1+4%)^4)/981.85
=(1*35/1.04+2*1*(1000*3.5%)/(1+4%)^2+3*1*(1000*3.5%)/(1+4%)^3+4*1*(1000*3.5%)/(1+4%)^4)/981.85
=(1*35/1.04+2*1*35/(1+4%)^2+3*1*(1000*3.5%)/(1+4%)^3+4*1*(1000*3.5%)/(1+4%)^4)/981.85
=(1*35/1.04+2*1*35/1.04^2+3*1*(1000*3.5%)/(1+4%)^3+4*1*(1000*3.5%)/(1+4%)^4)/981.85
=(1*35/1.04+2*1*35/1.04^2+3*1*35/(1+4%)^3+4*1*(1000*3.5%)/(1+4%)^4)/981.85
=(1*35/1.04+2*1*35/1.04^2+3*1*35/1.04^3+4*1*(1000*3.5%)/(1+4%)^4)/981.85
=(1*35/1.04+2*1*35/1.04^2+3*1*35/1.04^3+4*1*35/(1+4%)^4)/981.85
=(1*35/1.04+2*1*35/1.04^2+3*1*35/1.04^3+4*1*35/1.04^4)/981.85
=311.389986/981.85
=0.317146
Answer:(1*(1000*3.5%)/(1+4%)+2*1*(1000*3.5%)/(1+4%)^2+3*1*(1000*3.5%)/(1+4%)^3+4*1*(1000*3.5%)/(1+4%)^4)/981.85=0.317146
