lb

Step-by-step explanation:

Lila uses lb of flour to make the bread.

Since she uses   lb less to make bread than cookies then flour used to make the cookies =   -  

                                                    =  

                                                    =   lb

She used  lb more flour to make cookies than brownies then flour used to make brownies =   -
