C.$97.20
D.$218.70
Answer:
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
