[1/1 Formula]
    Work: Calculate the value of equation (20+18.0×0.7+19.4*3.4+19.2*0.8+19.8*4.1+20*1+22*1.6+24*4.3)*0.22-2*25*0.47 .
    Question type: Mathematical calculation
    Solution:
          (20+18.0×0.7+19.4*3.4+19.2*0.8+19.8*4.1+20*1+22*1.6+24*4.3)*0.22-2*25*0.47
        =353.5*0.22-2*25*0.47
        =77.77-2*25*0.47
        =77.77-50*0.47
        =77.77-23.5
        =54.27

    Answer:(20+18.0×0.7+19.4*3.4+19.2*0.8+19.8*4.1+20*1+22*1.6+24*4.3)*0.22-2*25*0.47=54.27
