Question

Lila decided to make more baked goods for the bake sale she used 1/8 lb less flour to make the bread then to make the cookies. She used 1/4 pound more flour to make cookies than to make brownies. If she used a half pound of flour to make bread how much flour did she use to make brownies

Answer 1

The total
`(3)/(8)` lb flour is used to make brownies.

Explanation:

Let x lb flour is used to make brownies.

She used 1/4 pound more flour to make cookies than to make brownies. So, the total flour is used to make cookies is

`x+(1)/(4)`

she used 1/8 lb less flour to make the bread then to make the cookies. So, the total flour is used to make bread is

`x+(1)/(4)-(1)/(8)`

It is given that she used a half pound of flour to make bread.

`x+(1)/(4)-(1)/(8)=(1)/(2)`

`x+(2-1)/(8)=(1)/(2)`

`(8x+1)/(8)=(1)/(2)`

`8x+1=4`

`8x=3`

`x=(3)/(8)`

Therefore total
`(3)/(8)` lb flour is used to make brownies.
