Answer: Marginal Benefit = 10 televisions
Explanation:
Marginal benefit is the additional benefits or revenue that is obtained from the production of one more unit or from running the assembly line for one more hour.
In 6 hours we produce 120 televisions.
If we run the assembly line for 1 more hour we produce a total of 130 televisions. That is in 7 hours we produce 130 television.
Thus, [tex]marginal benefit = \frac{130 - 120}{7 - 6}[/tex]
[tex]Marginal Benefit = 10 televisions[/tex]
