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:
The answer would be 22. Please mark me brainliest:D

5

Step-by-step explanation:</h3>
Let n represent the numerator of the original fraction, which is n/(n+4). After adding 1/2, the value is (2(n+4)+1)/(2(n+4)), so we have ...
n/(n+4) + 1/2 = (2(n+4)+1)/(2(n+4))
Simplifying gives ...
... (2n +(n+4))/(2(n+4)) = (2n +9)/(2(n+4))
Since the denominators are the same, we can work only with the numerators.
3n +4 = 2n +9
n = 5 . . . . . . . . . . . subtract 2n+4

The original fraction is 5/(5+4) = 5/9. Adding 1/2 gives ...
5/9 + 1/2 = 10/18 + 9/18 = 19/18
Note the numerator of this last fraction is 1 more than the denominator, which is twice the original denominator.
Answer:
y=21 when x =15
Step-by-step explanation:
Since you multiply 5 by 3 to get 15, you also multiply 7 by 3. Therefore y=21
