Formula => I=PRT
900=7500.R.2
R=900/15000

The question wants us to represent your the equation y - 4 = 6()
If we make s = Senior tickets,
11s+1s
to find the values of c and s,w
If we express s in terms of c on t
s=21-2c
replacing this value on the first equation, we obtain

Placing c=6 on s=21-2c, we have

Thus the senior ticket costs $9 and the child ticket cost $6
