To model the rental costs of tables from both Parties 'R Us and Rob's Rentals, we need to set up the linear equations based on the provided information.
For Parties 'R Us, the cost equation \( C \) is composed of a $60 delivery fee plus $4 for each table rented, represented by \( t \). Therefore, the equation is:
\[ C = 4t + 60 \]
For Rob's Rentals, the cost equation \( C \) has a $40 delivery fee plus $6 for each table rented, represented by \( t \). Therefore, the equation is:
\[ C = 6t + 40 \]
So, the pair of linear equations that model this situation is:
- Parties 'R Us: \( C = 4t + 60 \)
- Rob's Rentals: \( C = 6t + 40 \)
Out of the provided response options, none of them are correct. The correct equations should be as formulated above.
