To determine the break even number of yearbooks, equate the revenue with the total cost. Let x be the number of yearbooks sold so that the break even equation becomes,
15x = 12000 + 5x
The value of x is 1200. Therefore, the answer is letter B.
Answer:
B
Step-by-step explanation:
![~~~\left( \dfrac 1 3 \sqrt x - \dfrac 32 \sqrt y \right)^2\\\\\\=\left( \dfrac 13 \sqrt x \right)^2 + \left( \dfrac 32 \sqrt y \right)^2 - 2 \left(\dfrac 13 \sqrt x \right)\left( \dfrac 32 \sqrt y \right)\\\\\\=\dfrac 19 x+ \dfrac 94 y-\sqrt{xy}\\\\\\=\dfrac 19x - \sqrt{xy} + \dfrac 94 y](https://tex.z-dn.net/?f=~~~%5Cleft%28%20%5Cdfrac%201%203%20%5Csqrt%20x%20-%20%5Cdfrac%2032%20%5Csqrt%20y%20%5Cright%29%5E2%5C%5C%5C%5C%5C%5C%3D%5Cleft%28%20%5Cdfrac%2013%20%5Csqrt%20x%20%5Cright%29%5E2%20%2B%20%5Cleft%28%20%5Cdfrac%2032%20%5Csqrt%20y%20%5Cright%29%5E2%20-%202%20%5Cleft%28%5Cdfrac%2013%20%5Csqrt%20x%20%5Cright%29%5Cleft%28%20%5Cdfrac%2032%20%5Csqrt%20y%20%5Cright%29%5C%5C%5C%5C%5C%5C%3D%5Cdfrac%2019%20x%2B%20%5Cdfrac%2094%20y-%5Csqrt%7Bxy%7D%5C%5C%5C%5C%5C%5C%3D%5Cdfrac%2019x%20-%20%5Csqrt%7Bxy%7D%20%2B%20%5Cdfrac%2094%20y)
