    A)  \[\text{x = 70 (10 +15)}\]  

    B)  \[\text{x = 15 (70 +10)}\]

    C)  \[x\text{ }=\text{ }70\text{ }+(10\times 15)\]

    D)  \[\text{x = 20 (70+10+15)}\]

    Correct Answer: A

    Solution :

     Number of tables = 70 Total number of silver and gold balloons used to decorate each table =10+15 \[\therefore \]The required equation is x = 70 (10 + 15)
