Answer:
24 more chocolotae chip cookies are sold 
Step-by-step explanation:
CCC  7(15)+6    105+6=111
SC   6(15)-3      90-3 = 87
111-87 = 24
 
        
             
        
        
        
Let us start subtracting 3 cos theta both sides so that we may get all theta terms on left side only 
 It is now : 4 cos theta - 3 cos theta = - (sqrt3)/ 2
 1 cos theta = -( sqrt 3 ) /2 
we know cos (pi-x)= - cos x And cos (pi+ x)= - cos (x)
 ********* let us first use :
 - Cos ( pi - theta) = - ( sqrt 3 )/2
 this implies cos (pi- theta )= (sqrt 3) /2 
 cos ( pi - theta )= cos (pi /6)
 pi- theta = pi/6
 pi- pi/6 = theta 
 5 pi/6 = theta 
 one of teh answer is 5 pi/6 . another value of theta would be : 
 (2pi - 5pi/6)= 7pi/6 
Answer: 5 pi/6 and 7 pi/6
