Answer: 400 males and 800 females.
Step-by-step 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
