Answer

Explicación:

Paso 1: Definir la relación

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

Paso 2: Despejar $P_m$

Reordenando la ecuación anterior, obtenemos $P_m=P_j-\Delta P$. Sabemos que $P_j = 25.69$ y $\Delta P=- 0.75$.

Paso 3: Calcular $P_m$

$P_m=25.69-(-0.75)=25.69 + 0.75=26.44$

Respuesta:

$26.44$
