Question

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?

Answer 1

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"         
     $b=c-\frac{1}{8}$

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

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

From here you can solve for $w$ using back substitution.
