Ticket at a rugby leaque game cost $2.00 for children and $3.00 for adult.

$2319 was collected after selling 889 tickets.
How many adult tickets were sold?

How do you get 2 in 2a + 2c =1778

Let's assume the number of adult tickets sold is "x".

Since each adult ticket costs $3.00, the total amount collected from selling adult tickets would be 3 * x.

The number of child tickets sold can be calculated by subtracting the number of adult tickets sold from the total number of tickets sold: 889 - x.

Since each child ticket costs $2.00, the total amount collected from selling child tickets would be 2 * (889 - x).

The total amount collected from selling both adult and child tickets is given as $2319.

Therefore, we can set up the equation:
3x + 2(889 - x) = 2319

Now we can solve for x:
3x + 1778 - 2x = 2319
x + 1778 = 2319
x = 2319 - 1778
x = 541

Therefore, 541 adult tickets were sold.

To find the number of adult tickets sold, we need to set up an equation based on the given information.

Let's assume 'x' represents the number of adult tickets sold.

Given:
The price of a child's ticket = $2.00
The price of an adult's ticket = $3.00
The total amount collected = $2319.00
The total number of tickets sold = 889

Now, let's create the equation:

Total amount collected from child tickets + Total amount collected from adult tickets = Total amount collected

The total amount collected from child tickets can be found by multiplying the price of a child's ticket by the number of child tickets sold. Since we don't have the exact number of child tickets sold, we can represent it as (889 - x), as the total number of tickets sold minus the number of adult tickets sold gives us the number of child tickets sold.

Similarly, the total amount collected from adult tickets can be found by multiplying the price of an adult's ticket by the number of adult tickets sold, which is 'x'.

Therefore, the equation becomes:
($2.00) * (889 - x) + ($3.00) * (x) = $2319.00

Now we can solve this equation to find the value of 'x', which represents the number of adult tickets sold.

use what they have told you.

a+c = 889
3a+2c = 2319
Now just solve for a.
3a+2c = 2319
2a+2c = 1778
subtract, and you have
a = 541
