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"

b=c-(1)/(8)

2) "1/4 lb more flour to make cookies than to make brownies:

c=w+(1)/(4)

3) "she used 1/2 lb of flour ro make bread"

b = (1)/(2)

From here you can solve for
w using back substitution.
