=134.39+19×0.43+17.8×0.5+8×15.97+8.1×8.28+9.4×0.17+8.1×6.03
=134.39+8.17+17.8×0.5+8×15.97+8.1×8.28+9.4×0.17+8.1×6.03
=134.39+8.17+8.9+8×15.97+8.1×8.28+9.4×0.17+8.1×6.03
=134.39+8.17+8.9+127.76+8.1×8.28+9.4×0.17+8.1×6.03
=134.39+8.17+8.9+127.76+67.068+9.4×0.17+8.1×6.03
=134.39+8.17+8.9+127.76+67.068+1.598+8.1×6.03
=134.39+8.17+8.9+127.76+67.068+1.598+48.843
=142.56+8.9+127.76+67.068+1.598+48.843
=151.46+127.76+67.068+1.598+48.843
=279.22+67.068+1.598+48.843
=346.288+1.598+48.843
=347.886+48.843
=396.729
Answer:17.8×7.55+19×0.43+17.8×(8.48-0.43-7.55)+(17.8-9.8)×(16.47-8.48+0.43+7.55)+(17.9-9.8)×8.28+(19.2-9.8)×0.17+(17.9-9.8)×6.03=396.729
