[1/1 Formula]
    Work: Calculate the value of equation 720+720/(1-10%)×((70%+20%)×(1+20%)+15%) .
    Question type: Mathematical calculation
    Solution:
          720+720/(1-10%)×((70%+20%)×(1+20%)+15%)
        =720+720/0.9×((70%+20%)×(1+20%)+15%)
        =720+720/0.9×(0.9×(1+20%)+15%)
        =720+720/0.9×(0.9×1.2+15%)
        =720+720/0.9×1.23
        =720+800×1.23
        =720+984
        =1704

    Answer:720+720/(1-10%)×((70%+20%)×(1+20%)+15%)=1704
