Answer:
F^-1 (x) = 3x/2+5/4
Step-by-step explanation:
First, replace f(x) with y 
Replace every x with a y and replace every y with an x .
Solve the equation from Step 2 for y  
Replace y with f−1(x) f − 1 ( x ) 
Verify your work by checking that (f∘f−1)(x)=x ( f ∘ f − 1 ) ( x ) = x and (f−1∘f)(x)=x ( f − 1 ∘ f ) ( x ) = x are both true.
Hope this helps!  Stay Safe!
 
        
             
        
        
        
Answer:
She should leave a total of $78. 
Step-by-step explanation:
To find this, we first need to find the tip amount. We can do this by multiplying the total by the tip percentage. 
$65 * 20% = $13
Now that we have that, we need to add it to the cost. 
$65 + $13 = $78
