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
Hello! remember you have to write complete questions in order to get good and exact answers. Here I'll explain this in a general way assuming the following table:
As you can see, x increases in steps of 1 units. So let's check the difference in y:
So we have a constant difference and we can conclude the table represents a line. Since the line passes through then y is directly proportional to x, so we can write:
Then:
Finally, the equation of the line is:
