[1/1 Formula]
    Work: Calculate the value of equation 75/(1+7.5%)+75/(1+7.5%)^2+75/(1+7.5%)^3 .
    Question type: Mathematical calculation
    Solution:
          75/(1+7.5%)+75/(1+7.5%)^2+75/(1+7.5%)^3
        =75/1.075+75/(1+7.5%)^2+75/(1+7.5%)^3
        =75/1.075+75/1.075^2+75/(1+7.5%)^3
        =75/1.075+75/1.075^2+75/1.075^3
        =75/1.075+75/1.155625+75/1.075^3
        =75/1.075+75/1.155625+75/1.242296875
        =69.767442+75/1.155625+75/1.242296875
        =69.767442+64.899946+75/1.242296875
        =69.767442+64.899946+60.372043
        =134.667388+60.372043
        =195.039431

    Answer:75/(1+7.5%)+75/(1+7.5%)^2+75/(1+7.5%)^3=195.039431
