[1/1 Formula]
    Work: Calculate the value of equation 400*2*4+2500*2*0.67/2*4+7.5*2*80/12*2/2 .
    Question type: Mathematical calculation
    Solution:
          400*2*4+2500*2*0.67/2*4+7.5*2*80/12*2/2
        =800*4+2500*2*0.67/2*4+7.5*2*80/12*2/2
        =3200+2500*2*0.67/2*4+7.5*2*80/12*2/2
        =3200+5000*0.67/2*4+7.5*2*80/12*2/2
        =3200+3350/2*4+7.5*2*80/12*2/2
        =3200+1675*4+7.5*2*80/12*2/2
        =3200+6700+7.5*2*80/12*2/2
        =3200+6700+15*80/12*2/2
        =3200+6700+1200/12*2/2
        =3200+6700+100*2/2
        =3200+6700+200/2
        =3200+6700+100
        =9900+100
        =10000

    Answer:400*2*4+2500*2*0.67/2*4+7.5*2*80/12*2/2=10000
