Answer:

Step-by-step explanation:
Given: 
We have to find the value of 
Since Given 
Using trigonometric identity,

Thus, for   comparing , we have,
 comparing , we have,

We get,
 
Thus, 
 
        
                    
             
        
        
        
To answer the question above, I let x be the number of calendars sold. You may use any other letter as this is just for representation. The total income generated in selling calendars is calculated by multiplying the number of calendars with the price. That is,
                                   total income = 5x
If we let total income be y, our equation is further simplified into, 
                                            y = 5x
