Maybe something like:
200s + 105a + 200 = 1,000
You can use x and y instead of s for student and a for adult.
Are the adults and students charged the same? If so then:
200x + 105x + 200 = 1,000
        
                    
             
        
        
        
17.156 is the rational number, if the number can be put into fraction form then it is considered rational
        
                    
             
        
        
        
Answer:
Step-by-step explanation:
The total amount of punch that Jennifer made for her party is 5 Liters. Her brother made another 750 milliliters.
1000 milliliters = 1 liter
750 milliliters = 750/1000 = 0.75Liter
if they combine the two batches, the total amount made would be 
5 + 0.75 = 5.75Liter 
= 5.75 × 1000 = 5750 milliliters
The number of 180 milliliters servings would be 
5750/180 = 31 servings
There would be leftovers of 170 milliliters
 
        
             
        
        
        
The table tells you that f(x)=0 at x=-6 and -2
