Answer:
47 pizzas
Step-by-step explanation:
Dave makes 6 pizzas in the first hour it is open and 3 pizzas each hour after that. 
If the number of hours after the first hour  is represented as x, then the number of pizzas he makes after x hours is:
6 + 3x
Lauren makes 11 pizzas in the first hour and 3 pizzas each hour after that. Then:
11 + 3x
The pizzeria is open for 6 hours in all, that is, 5 hours after the first hour.
This means that:
x = 5
The total amount of pizzas that Dave and Lauren make is:
6 + 3x + 11 + 3x
=> 17 + 6x
Therefore, the total amount of pizza they make 5 hours after the first hour is: 
17 + 6(5) = 17 + 30 = 47 pizzas
 
        
             
        
        
        
Answer:
x=3
Step-by-step explanation:
(11-3)+3x+1 = 5x+3
8+3x+1 = 5x+3
9+3x= 5x+3
6=2x
x=3
