The pree tax amount count as 100%, then there's the 7% tax and lastly the 20% tip. therefore, one would pay (100+20+7)% of $84.00.
127% of $84.00
(127/100) * $84.00 = $106.68
        
             
        
        
        
Answer:

Step-by-step explanation:
We have the exponential function of the form: 

And it goes through the points (0, 13) and (3, 832). 
Hence, when we substitute in 0 for x, we should get 13 for y. Therefore: 

Since anything to the zeroth power is 1, this yields: 

So, we determined that the value of a is 13. 
So, our function is now: 

We will need to determine b. We know that y equals 832 when x is 3. Hence: 

Divide both sides by 13: 

Take the cube root of both sides: 

Hence, our b value is 4. 
Therefore, our entire equation is:
