Answer:
a. It would cost $77.50 to buy 5 tickets.
C(x)=17.5(5)-10
C(x)=87.50-10
C(x)=77.50
b. You can buy 8 tickets with $130
C(x)=17.5x-10
130=17.5x-10
Add 10 on both sides
140=17.5x
Divide 17.5 on both sides
8=x
Yes this answer is reasonable since 47 divided by 11 is close to 4. The answer is 4 2/71
