Suppose instead we are interested in the demand for a shared good (another way of thinking about a public good). Even though televisions aren't typically considered public goods, within a household it is reasonable to think of them this way. Suppose you and your SO (significant other) are considering buying a big-screen TV together. If you value the TV at $350 and your SO values it at $400 then the total household value would be $750. So, in your home 1 such TV would be demanded if they sell for no more than $750. Suppose you would value a 2nd TV at $150 and your SO would value a 2nd at $200, then you would demand 2 TVs if the price were no mor than $350, and so on.
