Work: Calculate the value of equation 75*(1/7%-1/(7%*(1+7%)^19))+1000/(1+7%)^19 .
Question type: Mathematical calculation
Solution:
75*(1/7%-1/(7%*(1+7%)^19))+1000/(1+7%)^19
=75*(1/7%-1/(7%*1.07^19))+1000/(1+7%)^19
=75*(1/7%-1/0.253157)+1000/(1+7%)^19
=75*10.335596+1000/(1+7%)^19
=75*10.335596+1000/1.07^19
=75*10.335596+1000/3.616527535033816
=775.1697+1000/3.616527535033816
=775.1697+276.508333
=1051.678033
Answer:75*(1/7%-1/(7%*(1+7%)^19))+1000/(1+7%)^19=1051.678033
