Answer:
   D.  210
Step-by-step explanation:
If b is the number of boys in the choir, the ratio of boys to girls is ...
   b/150 = 7/5
   b = 150(7/5) = 30(7) = 210
There are 210 boys in the choir.
 
        
             
        
        
        
5 + 8s = 15 + 3s
8s - 3s = 15 - 5
5s = 10
s = 10/5
s = 2 <=== they will charge the same at 2 sq ft
