C. $97.20

Step-by-step explanation:

Let the dinner bill be $x.

The tip given to the waiter is $14.58.

Also, it is given that the tip is 15% of the tip.

Thus we get the relation 15% of x = 14.58

i.e. 0.15x = 14.58

i.e.

i.e. x = 97.20

Hence, the amount of dinner bill before the tip is added is given by $97.20
