[1/1 Formula]
    Work: Calculate the value of equation (38.9+8/4×2)×(1+7%)×(1+9%)×85%-10.022 .
    Question type: Mathematical calculation
    Solution:
          (38.9+8/4×2)×(1+7%)×(1+9%)×85%-10.022
        =42.9×(1+7%)×(1+9%)×85%-10.022
        =42.9×1.07×(1+9%)×85%-10.022
        =42.9×1.07×1.09×85%-10.022
        =42.9×1.07×1.09×0.85-10.022
        =45.903×1.09×0.85-10.022
        =50.03427×0.85-10.022
        =42.529129-10.022
        =32.507129

    Answer:(38.9+8/4×2)×(1+7%)×(1+9%)×85%-10.022=32.507129
