first equation, combine that with the second and third equation.
S=.3D
S=.3*.4D
Put that into the last equation.
1) B+D+.12D=608
now, solve for B in the second equation
B=D/.4=2.5D Now put that in your equation 1) above, solve for D
S=.3D
S=.3*.4D
Put that into the last equation.
1) B+D+.12D=608
now, solve for B in the second equation
B=D/.4=2.5D Now put that in your equation 1) above, solve for D
