a) Pour dĂ©terminer quel manuel acheter, on compare le prix que l'on est prĂȘt Ă  dĂ©bourser pour le manuel usagĂ© et le prix que l'on est prĂȘt Ă  payer pour un manuel neuf.

Prix maximum pour manuel usagé : $120
Prix maximum pour manuel neuf : $140

Étant donnĂ© que le manuel usagĂ© coĂ»terait $100, il est plus avantageux d'acheter le manuel usagĂ©, car il est en dessous du prix maximum que l'on est prĂȘt Ă  payer pour un manuel neuf.

Donc, on achÚterait le manuel usagé à $100.

b) Le prix maximum qui ferait prĂ©fĂ©rer acheter le manuel usagĂ© est de $120, car c'est le montant maximum que l'on est prĂȘt Ă  payer pour le manuel usagĂ©.

c) Le prix que l'on paiera pour l'objet est de $100, car c'est le prix demandĂ© par l'ancien Ă©tudiant. Le prix est dĂ©terminĂ© par l'offre et la demande sur le marchĂ©, ainsi que par les limites de prix que l'acheteur est prĂȘt Ă  payer.

d) Les gains Ă  l'Ă©change peuvent ĂȘtre calculĂ©s en soustrayant le prix d'achat du manuel usagĂ© du prix du manuel neuf.

Gain à l'échange = Prix manuel neuf - Prix manuel usagé
Gain à l'échange = $140 - $100
Gain à l'échange = $40

Donc, les gains à l'échange seront d'au moins $40.

\textbf{Answer:}
a) On achÚterait le manuel usagé.
b) Le prix maximum pour le manuel usagé est de $120.
c) On paiera pour le manuel usagé est de $100. Le prix est déterminé par l'offre et la demande.
d) Les gains à l'échange sont d'au moins $40.
