Answer:
19 weeks
Step-by-step explanation:
Given equation:
P = w
Where,
w = the number of weeks he has taken piano lessons
p = the total number of pieces he has learned
how many weeks of piano lessons will Lamar need before he will be able to play a total of 19 pieces?
Find w when p = 19
P = w
p = 19
Since P = w 
19 = w
Therefore, 
w = 19
Lamar need 19 weeks before he will be able to play a total of 19 pieces
 
        
             
        
        
        

It is a positive-slope parabola with vertex of (0,16)    "concave up"
