Answer:
<h2>
<u>$52.5</u></h2>
Step-by-step explanation:
Step one:
given data
we are given that the linear function for the cost is c=3.5t
c is the cost and
t is the number of tickets.
We are told that t=15, to find c, let us put the value of t in the linear function for the cost
<u>This shows that 15 tickets will cost $52.5</u>
<u />
Take half of the middle coefficient.
Then square it.
-12/2 = -6
(-6)^2 = 36
c = 36
