[1/1 Formula]
    Work: Calculate the value of equation (20+18.5×0.5+20×4.1+19.1×2.9+21×2.5)×0.38-2×30×0.6 .
    Question type: Mathematical calculation
    Solution:
          (20+18.5×0.5+20×4.1+19.1×2.9+21×2.5)×0.38-2×30×0.6
        =219.14×0.38-2×30×0.6
        =83.2732-2×30×0.6
        =83.2732-60×0.6
        =83.2732-36
        =47.2732

    Answer:(20+18.5×0.5+20×4.1+19.1×2.9+21×2.5)×0.38-2×30×0.6=47.2732
