Divide commission amount by percentage:
83.50 / 0.40 = 208.75
Sales must be $208.75
 
        
             
        
        
        
Answer:
100
Step-by-step explanation:
130 - 30 = 100
 
        
             
        
        
        
False: The relation is a function because for each X value there is only one Y value.
True: The domain is the x values 
The lowest X value is 3 and the highest X value is 8
So 3<= x <= 8 is true
True: The range of a function is the Y values, which are 6,7,8,10
        
             
        
        
        

or in other words

3 is the opposite, and 5 is the hypotenuse.
You can use the pythagorean theorem to find the other side(adjacent)
a²+b²=c²
3²+b²=5²
9+b²=25 Subtract 9 on both sides
b²=16 Square root both sides
b = √16
b = 4
So the adjacent is 4. 
tan theta = opposite/adjacent
tan theta = 3/4
