To model the situation, we need to represent the total cost \( C \) for each rental service in terms of the number of tables \( t \).
For Parties ‘R Us:
- The delivery fee is $60, and the cost per table is $4. Thus, the equation for Parties ‘R Us is: \[ C = 4t + 60 \]
For Rob's Rentals:
- The delivery fee is $40, and the cost per table is $6. Thus, the equation for Rob's Rentals is: \[ C = 6t + 40 \]
So the pair of linear equations that model this situation is:
- Parties ‘R Us: \( C = 4t + 60 \)
- Rob’s Rentals: \( C = 6t + 40 \)
Based on the options provided, the correct response is: Parties ‘R Us: \( C = 4t + 60 \); Rob’s Rentals: \( C = 6t + 40 \).
