In a survey of 300 employees, a Venn diagram with three overlapping circles represents those who like Coffee ($C$), Tea ($T$), and Juice ($J$). The regions show: $|C \text{ only}| = 50$, $|T \text{ only}| = 45$, $|J \text{ only}| = 40$, $|C \cap T \text{ only}| = 35$, $|C \cap J \text{ only}| = 30$, $|T \cap J \text{ only}| = 25$, and $|C \cap T \cap J| = 20$. How many employees like none of these beverages?
