Option D. x = number of hats
Step-by-step explanation:
Let number of hats sold by the companies is x and revenue generated by companies are y and y' respectively.
For company A.
Company sells hats for $11 per hat and a fixed fee of $7 for shipping and handling
So, revenue generated by company A by selling x hats, y = 11x + 7(1)
Similarly for company B.
Company B sells hats for $8 per hat and a fix fee of $16 for shipping and handling
So, revenue generated by company B will be y' = 8x + 16(2)
From this system of equations we can find the number of hats.
But this is possible when total cost of an order for both the companies is same, means y = y'
It's evident from the equations that x will represent number of hats.
Option D. x = number of hats is the correct option.
