A local amusement park charges $21.50 per daily adult ticket and $14.75 per daily child's ticket. A group of 12 people paid $204

Answer:

$x+y=12$

$21.50x+14.75y=204$

Step-by-step explanation:

Let x be the number of adult tickets and y be the number of children's tickets.

We are given that there are total 12 people. Therefore, we can set:

$x+y=12$

Moreover, we are given that an adult ticket costs $21.50 and a child's ticket costs $14.75, therefore, cost of x adult tickets will be $21.50x$ and cost of y children's ticket will be $14.75y$ . We can form the second equation by setting the total cost of tickets as:
