Work: Calculate the value of equation 50/(1+0.2)+50/(1+0.2)^(2)+50/(1+0.2)^(3)+50/(1+0.2)^(4)-150 .
Question type: Mathematical calculation
Solution:
50/(1+0.2)+50/(1+0.2)^(2)+50/(1+0.2)^(3)+50/(1+0.2)^(4)-150
=50/1.2+50/(1+0.2)^(2)+50/(1+0.2)^(3)+50/(1+0.2)^(4)-150
=50/1.2+50/1.2^(2)+50/(1+0.2)^(3)+50/(1+0.2)^(4)-150
=50/1.2+50/1.2^2+50/(1+0.2)^(3)+50/(1+0.2)^(4)-150
=50/1.2+50/1.2^2+50/1.2^(3)+50/(1+0.2)^(4)-150
=50/1.2+50/1.2^2+50/1.2^3+50/(1+0.2)^(4)-150
=50/1.2+50/1.2^2+50/1.2^3+50/1.2^(4)-150
=50/1.2+50/1.2^2+50/1.2^3+50/1.2^4-150
=50/1.2+50/1.44+50/1.2^3+50/1.2^4-150
=50/1.2+50/1.44+50/1.728+50/1.2^4-150
=50/1.2+50/1.44+50/1.728+50/2.0736-150
=41.666667+50/1.44+50/1.728+50/2.0736-150
=41.666667+34.722222+50/1.728+50/2.0736-150
=41.666667+34.722222+28.935185+50/2.0736-150
=41.666667+34.722222+28.935185+24.112654-150
=76.388889+28.935185+24.112654-150
=105.324074+24.112654-150
=129.436728-150
=-20.563272
Answer:50/(1+0.2)+50/(1+0.2)^(2)+50/(1+0.2)^(3)+50/(1+0.2)^(4)-150=-20.563272
