Answer

Explanation:

Step1: Definir la relación

El precio de cierre jueves es igual al precio de cierre miércoles más el cambio. Llamemos $P_m$ al precio de cierre miércoles y $P_j$ al precio de cierre jueves y $\Delta P$ al cambio. Entonces $P_j=P_m + \Delta P$.

Step2: Despejar $P_m$

Re - organizando la ecuación anterior, obtenemos $P_m=P_j-\Delta P$. Sabemos que $P_j = 17.29$ dólares y $\Delta P=- 0.40$ dólares.

Step3: Calcular $P_m$

Sustituyendo los valores, $P_m=17.29-(-0.40)=17.29 + 0.40=17.69$ dólares.

Answer:

$17.69$ dólares, es decir, la última opción.
