Answer:
c+a=2,200
1.50c+4c=5,050
Explanation:
We know that on one day, 2,200 people entered the fair.
So, using the variables, c/a, we know that c+a=2,200
This gives us our first equation in this system of equations.
We are also given that a total of $5,050 was made. $1.50 is a children ticket/admission fee and $4 per adult.
So:
1.50c+4c=5,050
Thus our system of equations looks like:
c+a=2,200
1.50c+4c=5,050
Hope this helps! :)
