#39# cookies

Explanation:

Brenda baked #24# cookies

since Giselle baked twice as many as Brenda, she baked 48
#(24)(2)#

Ellen baked 9 fewer than Brenda so subtract
#48-9=39#

if you add up the total of cookies you get #111#

#24+48+39=111#

(to get the answer for one person, you may just have to plug in random numbers to find out what works)
