    题型：数学计算
    解:
          3+3.8+2.2+3.6+3.5+2+2.85+1.35+1.1+8.6+1.85+1.5+1.1+2.3+2.9+2.3+2.8+1+3.2
        =6.8+2.2+3.6+3.5+2+2.85+1.35+1.1+8.6+1.85+1.5+1.1+2.3+2.9+2.3+2.8+1+3.2
        =9+3.6+3.5+2+2.85+1.35+1.1+8.6+1.85+1.5+1.1+2.3+2.9+2.3+2.8+1+3.2
        =12.6+3.5+2+2.85+1.35+1.1+8.6+1.85+1.5+1.1+2.3+2.9+2.3+2.8+1+3.2
        =16.1+2+2.85+1.35+1.1+8.6+1.85+1.5+1.1+2.3+2.9+2.3+2.8+1+3.2
        =18.1+2.85+1.35+1.1+8.6+1.85+1.5+1.1+2.3+2.9+2.3+2.8+1+3.2
        =20.95+1.35+1.1+8.6+1.85+1.5+1.1+2.3+2.9+2.3+2.8+1+3.2
        =22.3+1.1+8.6+1.85+1.5+1.1+2.3+2.9+2.3+2.8+1+3.2
        =23.4+8.6+1.85+1.5+1.1+2.3+2.9+2.3+2.8+1+3.2
        =32+1.85+1.5+1.1+2.3+2.9+2.3+2.8+1+3.2
        =33.85+1.5+1.1+2.3+2.9+2.3+2.8+1+3.2
        =35.35+1.1+2.3+2.9+2.3+2.8+1+3.2
        =36.45+2.3+2.9+2.3+2.8+1+3.2
        =38.75+2.9+2.3+2.8+1+3.2
        =41.65+2.3+2.8+1+3.2
        =43.95+2.8+1+3.2
        =46.75+1+3.2
        =47.75+3.2
        =50.95
    答案:3+3.8+2.2+3.6+3.5+2+2.85+1.35+1.1+8.6+1.85+1.5+1.1+2.3+2.9+2.3+2.8+1+3.2=50.95
