[1/1 Formula]
    Work: Calculate the value of equation (20+18.8×2.85+20.2×2.62+19.2×1.02+18.8×4.22)×0.61-2×24.2×0.79 .
    Question type: Mathematical calculation
    Solution:
          (20+18.8×2.85+20.2×2.62+19.2×1.02+18.8×4.22)×0.61-2×24.2×0.79
        =225.424×0.61-2×24.2×0.79
        =137.50864-2×24.2×0.79
        =137.50864-48.4×0.79
        =137.50864-38.236
        =99.27264

    Answer:(20+18.8×2.85+20.2×2.62+19.2×1.02+18.8×4.22)×0.61-2×24.2×0.79=99.27264
