[1/1 Formula]
    Work: Calculate the value of equation 45*(1000*0.2)+50*(1000-1000*0.2)*0.8+50*0.8*100 .
    Question type: Mathematical calculation
    Solution:
          45*(1000*0.2)+50*(1000-1000*0.2)*0.8+50*0.8*100
        =45*200+50*(1000-1000*0.2)*0.8+50*0.8*100
        =45*200+50*800*0.8+50*0.8*100
        =9000+50*800*0.8+50*0.8*100
        =9000+40000*0.8+50*0.8*100
        =9000+32000+50*0.8*100
        =9000+32000+40*100
        =9000+32000+4000
        =41000+4000
        =45000

    Answer:45*(1000*0.2)+50*(1000-1000*0.2)*0.8+50*0.8*100=45000
