The seeds model makes sense in normal economic times. In weak or strong economies, your demand curve may change. Assume that the demand curve, more generally, is given by 𝑞𝑑(𝑝)=𝑎(300−25𝑝)
and the supply curve is given by 𝑞𝑠(𝑝)=𝑎(50𝑝)
where a is a parameter that indicates the strength of the overall economy. In a stronger than normal economy (a higher equilibrium quantity of seed packets) which sentence best describes the parameter a?
