The equestion is
2x^2-5x-12=0
we can either try to factor, or use quadratic formula
trial and errot
(x-4)(2x+3)=0
set to zero
x-4=0
x=4
2x+3=0
2x=-3
x=-3/2
x=-3/2 or 4
If one child bought a ticket, we would calculate the total cost by multiplying $4.50 by 1. If two children bought tickets, we could calculate the total cost by multiplying the total cost by 2. So, the total number of tickets will always be 4.50 * the total number of tickets.
Because the number of children who bought tickets is represented by c and the number of adults who bought tickets are represented by a, our equation should look like:
$4.50c + $4.50a = money earned
Answer:
Option A is correct answer
