I got this when I used substitution: a = 2200 – c
4(2200 – c) + 1.5c = 5050
8800 – 4c + 1.5c = 5050
The admission fee at a small fair is $1.50 for children and $4.00 for adults. On a certain day, 2200 people enter the fair and $5050 is collected. How many children and how many adults attended
8800 – 2.5c = 5050
–2.5c = –3750
c = 1500
a = 2200 – (1500) = 700
I'm a little confused on how to find where to use elimination and how to use it
