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