I don't get this problem. Lila decided to make kore baked goods for the bake sale. She used 1 / 8 lb less flour to make bread than to make cookies. She used 1/4 lb more flour to make cookies than to make brownies. If she used 1/2 lb of flour to make bread , how much flour did she use to make the brownies?

Start by taking the information we know, and write equations to represent the realationships:

1) "1/8 lbs less flour to make bread than to make cookies"         
     [tex] b=c-\frac{1}{8}[/tex]

2) "1/4 lb more flour to make cookies than to make brownies:
     [tex] c=w+\frac{1}{4}[/tex]

3) "she used 1/2 lb of flour ro make bread"
    [tex] b = \frac{1}{2}[/tex]

From here you can solve for [tex]w[/tex] using back substitution.
