The two numbers are illustrations of system of equations 
The two numbers are 2.7 and 37.3
<h3>How to determine the two numbers?</h3>
Let the numbers be x and y.
So, we have the following equations
x + y = 40
xy = 100
To determine the value of the variables, we simply plot the graph of both equations
From the graph, we have the following result
(x,y) = (2.7, 37.3)
Hence, the two numbers are 2.7 and 37.3

   inequality could be used to find the number of models Walt builds which is Dwight builds at most 9 and Walt builds at most 4 .
  inequality could be used to find the number of models Walt builds which is Dwight builds at most 9 and Walt builds at most 4 .
<u>Step-by-step explanation:</u>
Here we have , Dwight and Walt are building model cars. Dwight builds 7 fewer models than 4 times the number Walt builds.Dwight builds at most 9 models. We need to find Which inequality could be used to find the number of models Walt builds . Let's find out:
Let the  the number Walt builds is x , So Dwight builds 7 fewer models than 4 times the number Walt builds i.e.
⇒ 
But , according to question Dwight builds at most 9 models i.e.
⇒ 
⇒ 
⇒ 
⇒ 
Therefore ,   inequality could be used to find the number of models Walt builds which is Dwight builds at most 9 and Walt builds at most 4 .
  inequality could be used to find the number of models Walt builds which is Dwight builds at most 9 and Walt builds at most 4 .
 
        
                    
             
        
        
        
Given:
- total number of masks= 200
- cost of 1 mask= Rs. 5
 so, total cost fir 200 masks=
 200×5
 = 1000
 therefore, Joe paid Rs. 1000 altogether.
