a = (1+0.2)p
This equation is used to calculate the quantity of lemonade. 
<u>Step-by-step explanation:</u>
Let the quality of lemonade in lans glass be 'a' 
Quantity of lemonade in patricias glass = p ounces
Lan pours 20% more than Patricia 
a = (1+0.2)p
This equation is used to calculate the quantity of lemonade
 
        
                    
             
        
        
        
1 + 1 = 2
2 + 2 = 4
4 + 3 = 7
7 + 4 = 11
11 + 5 = 16
16 + 6 = 22
22 + 7 = 29
29 + 8 = 37
sorry that I do not know the equation for this problem...but ur next 3 numbers are : 22,29,37.....so ur answer is D
