Answer: 20
Explanation: Alright, so basically you’re going to want to use PEMDAS (Parenthesis, Exponents, Multiplication/ Division, Addition/ Subtraction) 
* just means multiply.. sooo the problem looks like this: 
6x(12-7.5)-7 
We’ll start at the parentheses :) 
So (12-7.5) = 4.5 
Now our problem looks like: 6x(4.5)-7
Following PEMDAS, the next thing to come up is multiplication! So we’re going to multiply 6 by 4.5 ...
6x4.5=27 
After this our problem looks like: 27-7
So now it’s just simple math...
27-7= 20
 
        
                    
             
        
        
        
Answer:
$184.5
Step-by-step explanation:
so we know they are charging x hours for renting plus a flat rent fee of 32.5
r(x)= 9.5 x + 32.5
r(16)= 9.5 (16) + 32.5
r(16)= 152+ 32.5
r=$184.5
