Let the price of a silver ticket be \( x \) dollars. Then, the price of a gold ticket would be \( x + 8 \) dollars.
Patrick bought 10 silver tickets and 10 gold tickets, so the total cost can be expressed as follows:
\[ 10x + 10(x + 8) = 140 \]
Now, simplify the equation:
\[ 10x + 10x + 80 = 140 \] \[ 20x + 80 = 140 \]
Next, subtract 80 from both sides:
\[ 20x = 60 \]
Now, divide both sides by 20:
\[ x = 3 \]
So, the price of a silver ticket is \( x = 3 \) dollars. To find the price of a gold ticket:
\[ x + 8 = 3 + 8 = 11 \]
Thus, the price of each ticket is:
\[ \text{Silver ticket: } $3 \] \[ \text{Gold ticket: } $11 \]
The final answer is:
- Silver ticket: $3
- Gold ticket: $11
