Question type: Mathematical calculation
Solution:
18.69×(1.78/3+15.1+2.9)+2077.84×(15.1/3×(2×35.68+239.53)/(35.68+239.53)+2.9)+282.18×(2.29/3×(2×115.01+131.44)/(115.01+131.44))
=18.69×18.593333+2077.84×(15.1/3×(2×35.68+239.53)/(35.68+239.53)+2.9)+282.18×(2.29/3×(2×115.01+131.44)/(115.01+131.44))
=18.69×18.593333+2077.84×(15.1/3×310.89/(35.68+239.53)+2.9)+282.18×(2.29/3×(2×115.01+131.44)/(115.01+131.44))
=18.69×18.593333+2077.84×(15.1/3×310.89/275.21+2.9)+282.18×(2.29/3×(2×115.01+131.44)/(115.01+131.44))
=18.69×18.593333+2077.84×8.585887+282.18×(2.29/3×(2×115.01+131.44)/(115.01+131.44))
=18.69×18.593333+2077.84×8.585887+282.18×(2.29/3×361.46/(115.01+131.44))
=18.69×18.593333+2077.84×8.585887+282.18×(2.29/3×361.46/246.45)
=18.69×18.593333+2077.84×8.585887+282.18×1.119555
=347.509394+2077.84×8.585887+282.18×1.119555
=347.509394+17840.099444+282.18×1.119555
=347.509394+17840.099444+315.91603
=18187.608838+315.91603
=18503.524868
Answer:18.69×(1.78/3+15.1+2.9)+2077.84×(15.1/3×(2×35.68+239.53)/(35.68+239.53)+2.9)+282.18×(2.29/3×(2×115.01+131.44)/(115.01+131.44))=18503.524868
