Let's denote the cost of an adult ticket as \( A \) and the cost of a child ticket as \( C \). According to the information you've provided, we have the following equations:
1. The total cost for three adult tickets and three child tickets is \( 75 \):
\[
3A + 3C = 75
\]
2. The cost of each child ticket is $3 less than the cost of each adult ticket:
\[
C = A - 3
\]
Now, we can substitute the second equation into the first equation.
Substituting \( C \) in the first equation:
\[
3A + 3(A - 3) = 75
\]
Expanding the equation:
\[
3A + 3A - 9 = 75
\]
\[
6A - 9 = 75
\]
Now, add 9 to both sides:
\[
6A = 84
\]
Now, divide both sides by 6:
\[
A = 14
\]
Now that we have the cost of an adult ticket, we can find the cost of a child ticket using the second equation:
\[
C = A - 3 = 14 - 3 = 11
\]
So, the costs of the tickets are:
- Adult ticket: \( \$14 \)
- Child ticket: \( \$11 \)
