Answer: She used 3/8 lb of flour to make the bownies.
Explanation:
Hi, to answer this question we have to write equations with the information given:
- She used 1/2 lb of flour to make bread
Bread = 1/2
- She used 1/8 lb less flour to make bread than to make cookies.
Bread = cookies -1/8
Since bread= 1/2
(1/2) = cookies -1/8
1/2 + 1/8 = cookies
Cookies = 1/2+ 1/8 = 4/8+1/8=5/8
- She used 1/4 lb more to make cookies than to make brownies.
Cookies = brownies + 1/4
Since cookies=5/8
5/8 = brownies + 1/4
5/8 -1/4 = brownies
Brownies = 5/8-1/4 = 5/8 - 2/8 = 3/8
She used 3/8 lb of flour to make the brownies.
