To check which option fits the total of $75 for three adult tickets and three child tickets, we will do the math for each pair of prices provided.
-
Option 1: Adult ticket = $11, Child ticket = $8 \[ \text{Total cost} = 3 \times 11 + 3 \times 8 = 33 + 24 = 57 \quad (\text{Not } 75) \]
-
Option 2: Adult ticket = $12.50, Child ticket = $9.50 \[ \text{Total cost} = 3 \times 12.50 + 3 \times 9.50 = 37.5 + 28.5 = 66 \quad (\text{Not } 75) \]
-
Option 3: Adult ticket = $14, Child ticket = $11 \[ \text{Total cost} = 3 \times 14 + 3 \times 11 = 42 + 33 = 75 \quad (\text{This is correct}) \]
-
Option 4: Adult ticket = $8, Child ticket = $5 \[ \text{Total cost} = 3 \times 8 + 3 \times 5 = 24 + 15 = 39 \quad (\text{Not } 75) \]
The correct prices for the tickets are:
- Adult ticket = $14
- Child ticket = $11
