To model the situation with linear equations based on the given pricing structure for each rental company, we can write the equations as follows:
**Parties ‘R Us:**
- They charge a delivery fee of $60 and $4 per table. Thus, the equation for Parties 'R Us will be:
\[
C = 4t + 60
\]
**Rob’s Rentals:**
- They charge a delivery fee of $40 and $6 per table. Therefore, the equation for Rob's Rentals will be:
\[
C = 6t + 40
\]
So, the pair of linear equations that model this situation is:
- Parties ‘R Us: \( C = 4t + 60 \)
- Rob’s Rentals: \( C = 6t + 40 \)
None of the provided options exactly match this correct formulation, but ensure to check the options properly, as the correct interpretation leads us to the equations mentioned above.
