    题型：数学计算
    解:
          ((4.78+1.3)×2×0.5+(5.88+2)×2×0.5+(6.98+2.8)×2×0.5)×1+((5.08+1.3)×2×0.5+(6.18+2)×2×0.5+(7.28+2.8)×2×0.5)×1
        =(6.08×2×0.5+(5.88+2)×2×0.5+(6.98+2.8)×2×0.5)×1+((5.08+1.3)×2×0.5+(6.18+2)×2×0.5+(7.28+2.8)×2×0.5)×1
        =(6.08×2×0.5+7.88×2×0.5+(6.98+2.8)×2×0.5)×1+((5.08+1.3)×2×0.5+(6.18+2)×2×0.5+(7.28+2.8)×2×0.5)×1
        =(6.08×2×0.5+7.88×2×0.5+9.78×2×0.5)×1+((5.08+1.3)×2×0.5+(6.18+2)×2×0.5+(7.28+2.8)×2×0.5)×1
        =23.74×1+((5.08+1.3)×2×0.5+(6.18+2)×2×0.5+(7.28+2.8)×2×0.5)×1
        =23.74×1+(6.38×2×0.5+(6.18+2)×2×0.5+(7.28+2.8)×2×0.5)×1
        =23.74×1+(6.38×2×0.5+8.18×2×0.5+(7.28+2.8)×2×0.5)×1
        =23.74×1+(6.38×2×0.5+8.18×2×0.5+10.08×2×0.5)×1
        =23.74×1+24.64×1
        =23.74+24.64×1
        =23.74+24.64
        =48.38
    答案:((4.78+1.3)×2×0.5+(5.88+2)×2×0.5+(6.98+2.8)×2×0.5)×1+((5.08+1.3)×2×0.5+(6.18+2)×2×0.5+(7.28+2.8)×2×0.5)×1=48.38
