Nomad,
Its something I need to have.

Math 
Amanda,
5b+9m=150.5
9b+5m=175.7 if you add them you have one equation.
14b+14m=326.2
14(b+m)=326.2
b+m=23.3
b=23.3m
sub. this back into one the original equations
9(23.3m)+5m=175.5
209.79m+5m=175.5
4m=34.2
m=8.55
Plug that into the other equation
5b+9(8.55)=150.5
5b+76.95=150.5
5b=73.55
b=14.71
