[1/1 Formula]
    Work: Calculate the value of equation 400*5*4+2500*2*0.67/2*4+7.5*2*80/12*3/2 .
    Question type: Mathematical calculation
    Solution:
          400*5*4+2500*2*0.67/2*4+7.5*2*80/12*3/2
        =2000*4+2500*2*0.67/2*4+7.5*2*80/12*3/2
        =8000+2500*2*0.67/2*4+7.5*2*80/12*3/2
        =8000+5000*0.67/2*4+7.5*2*80/12*3/2
        =8000+3350/2*4+7.5*2*80/12*3/2
        =8000+1675*4+7.5*2*80/12*3/2
        =8000+6700+7.5*2*80/12*3/2
        =8000+6700+15*80/12*3/2
        =8000+6700+1200/12*3/2
        =8000+6700+100*3/2
        =8000+6700+300/2
        =8000+6700+150
        =14700+150
        =14850

    Answer:400*5*4+2500*2*0.67/2*4+7.5*2*80/12*3/2=14850
