Answer:
A = B + 15
Step-by-step explanation:
Let Diane sold B books in one hour,
Additional earning by selling 1 book = 1$
Additional earning by selling B books = Number of books sold × Additional earning by selling one book
= B × ($1.00)
= $B 
Fixed earning of Diane in one hour of part time = $15
Total earnings = B + 15
A = B + 15
Table to find the input-output values for the graph,
A      15      16        17      18
B       0        1          2       3
Now we can plot the points on the graph.
 
        
             
        
        
        
According to the diagram the answer is 36degree
        
             
        
        
        
2p-1q is the answer 
5p+2q-3p-3q
isolate the variables:
5p-3p+2q-3q
simplify:
2p-1q
that is the answer!
