[1/1 Formula]
    Work: Calculate the value of equation 0.03*30%+0.12*30%-0.08*40% .
    Question type: Mathematical calculation
    Solution:
          0.03*30%+0.12*30%-0.08*40%
        =0.03*0.3+0.12*30%-0.08*40%
        =0.03*0.3+0.12*0.3-0.08*40%
        =0.03*0.3+0.12*0.3-0.08*0.4
        =0.009+0.12*0.3-0.08*0.4
        =0.009+0.036-0.08*0.4
        =0.009+0.036-0.032
        =0.045-0.032
        =0.013

    Answer:0.03*30%+0.12*30%-0.08*40%=0.013
