Answer: 400 males and 800 females.

Explanation:

Hi, to answer this question we have to write a system of equations:

f +m =1200 (A marketing company surveys 1,200 people, females and males )

f =2 m (they surveyed twice as many females as males )

Where:

  • f : number of females
  • m: number of males

Replacing the value of f in the first equation:

(2m)+m = 1200

3m =1200

m= 1200/3

m=400

Replacing the value of m in the second equation

f= 2m

f = 2 (400)

f= 800

Feel free to ask for more if needed or if you did not understand something.
