Work: Calculate the value of equation 100/(1+7%)+100/(1+7%)^2+100/(1+7%)^3+100/(1+7%)^4+1000/(1+7%)^4 .
Question type: Mathematical calculation
Solution:
100/(1+7%)+100/(1+7%)^2+100/(1+7%)^3+100/(1+7%)^4+1000/(1+7%)^4
=100/1.07+100/(1+7%)^2+100/(1+7%)^3+100/(1+7%)^4+1000/(1+7%)^4
=100/1.07+100/1.07^2+100/(1+7%)^3+100/(1+7%)^4+1000/(1+7%)^4
=100/1.07+100/1.07^2+100/1.07^3+100/(1+7%)^4+1000/(1+7%)^4
=100/1.07+100/1.07^2+100/1.07^3+100/1.07^4+1000/(1+7%)^4
=100/1.07+100/1.07^2+100/1.07^3+100/1.07^4+1000/1.07^4
=100/1.07+100/1.1449+100/1.07^3+100/1.07^4+1000/1.07^4
=100/1.07+100/1.1449+100/1.225043+100/1.07^4+1000/1.07^4
=100/1.07+100/1.1449+100/1.225043+100/1.31079601+1000/1.07^4
=100/1.07+100/1.1449+100/1.225043+100/1.31079601+1000/1.31079601
=93.457944+100/1.1449+100/1.225043+100/1.31079601+1000/1.31079601
=93.457944+87.343873+100/1.225043+100/1.31079601+1000/1.31079601
=93.457944+87.343873+81.629788+100/1.31079601+1000/1.31079601
=93.457944+87.343873+81.629788+76.289521+1000/1.31079601
=93.457944+87.343873+81.629788+76.289521+762.895212
=180.801817+81.629788+76.289521+762.895212
=262.431605+76.289521+762.895212
=338.721126+762.895212
=1101.616338
Answer:100/(1+7%)+100/(1+7%)^2+100/(1+7%)^3+100/(1+7%)^4+1000/(1+7%)^4=1101.616338
