    题型：数学计算
    解:
          (3064.22×10^3)/(0.91×298×10^2×215)+(0.975×381.41×10^6+1×122.57×10^6)/(1.15×4.31×10^6×(1-(0.8×3064.22×10^3)/(20059.87×10^3))×215)
        =3064220/(0.91×298×10^2×215)+(0.975×381.41×10^6+1×122.57×10^6)/(1.15×4.31×10^6×(1-(0.8×3064.22×10^3)/(20059.87×10^3))×215)
        =3064220/5830370+(0.975×381.41×10^6+1×122.57×10^6)/(1.15×4.31×10^6×(1-(0.8×3064.22×10^3)/(20059.87×10^3))×215)
        =3064220/5830370+494444750/(1.15×4.31×10^6×(1-(0.8×3064.22×10^3)/(20059.87×10^3))×215)
        =3064220/5830370+494444750/(1.15×4.31×10^6×(1-2451376/(20059.87×10^3))×215)
        =3064220/5830370+494444750/(1.15×4.31×10^6×(1-2451376/20059870)×215)
        =3064220/5830370+494444750/(1.15×4.31×10^6×0.877797×215)
        =3064220/5830370+494444750/935422178.5575
        =0.525562+494444750/935422178.5575
        =0.525562+0.528579
        =1.054141
    答案:(3064.22×10^3)/(0.91×298×10^2×215)+(0.975×381.41×10^6+1×122.57×10^6)/(1.15×4.31×10^6×(1-(0.8×3064.22×10^3)/(20059.87×10^3))×215)=1.054141
