• A. $\frac{8}{5}lb$
• B. $1\frac{2}{5}lb$
• C. $\frac{7}{8}lb$
• D. $4lb$

Answer 1

The correct option is B $1\frac{2}{5}lb$

Amount of flour $=1lb$
Amount of butter$=\frac{2}{5}lb$
The total weight of the cookie mixture $=1+\frac{2}{5}=\frac{5}{5}+\frac{2}{5}=\frac{5+2}{5}=\frac{7}{5}=1\frac{2}{5}lb$
The total weight of the mixture $=1\frac{2}{5}lb$
