Answer:
As per the statement: Sally made 500 gingerbread men.
⇒Total gingerbread men made = 500
It is also given that: she sold 3/4 of them and gave away 2/5 of the remainder.
⇒ She sold = [tex]\frac{3}{4} \times 500 = 375[/tex] gingerbread men.
Remaining she left gingerbread men= [tex]500 -375 = 125[/tex]
then,
she gave away = 2/5 of the remaining gingerbread men
⇒[tex]\frac{2}{5} \times 125 = 2 \times 25=50[/tex]
Therefore, 50 gingerbread men did she give away.
