Work: Calculate the value of equation -150000+120000/(1+10%)+110000/(1+10%)^2+95000/(1+10%)^3+80000/(1+10%)^4 .
Question type: Mathematical calculation
Solution:
-150000+120000/(1+10%)+110000/(1+10%)^2+95000/(1+10%)^3+80000/(1+10%)^4
=-150000+120000/1.1+110000/(1+10%)^2+95000/(1+10%)^3+80000/(1+10%)^4
=-150000+120000/1.1+110000/1.1^2+95000/(1+10%)^3+80000/(1+10%)^4
=-150000+120000/1.1+110000/1.1^2+95000/1.1^3+80000/(1+10%)^4
=-150000+120000/1.1+110000/1.1^2+95000/1.1^3+80000/1.1^4
=-150000+120000/1.1+110000/1.21+95000/1.1^3+80000/1.1^4
=-150000+120000/1.1+110000/1.21+95000/1.331+80000/1.1^4
=-150000+120000/1.1+110000/1.21+95000/1.331+80000/1.4641

=-40909.090909+90909.090909+71374.906086+54641.076429
=50000+71374.906086+54641.076429
=121374.906086+54641.076429
=176015.982515
Answer:-150000+120000/(1+10%)+110000/(1+10%)^2+95000/(1+10%)^3+80000/(1+10%)^4=176015.982515
