Work: Calculate the value of equation 0.8×18+0.9×18.3+20.4×16.9+1.9×19.2+1×18+7.46×18.7+50 .
Question type: Mathematical calculation
Solution:
0.8×18+0.9×18.3+20.4×16.9+1.9×19.2+1×18+7.46×18.7+50
=14.4+0.9×18.3+20.4×16.9+1.9×19.2+1×18+7.46×18.7+50
=14.4+16.47+20.4×16.9+1.9×19.2+1×18+7.46×18.7+50
=14.4+16.47+344.76+1.9×19.2+1×18+7.46×18.7+50
=14.4+16.47+344.76+36.48+1×18+7.46×18.7+50
=14.4+16.47+344.76+36.48+18+7.46×18.7+50
=14.4+16.47+344.76+36.48+18+139.502+50
=30.87+344.76+36.48+18+139.502+50
=375.63+36.48+18+139.502+50
=412.11+18+139.502+50
=430.11+139.502+50
=569.612+50
=619.612
Answer:0.8×18+0.9×18.3+20.4×16.9+1.9×19.2+1×18+7.46×18.7+50=619.612
