Answer:

Se requiere un 20 por ciento de descuento.

Step-by-step explanation:

(This exercise has been presented in Spanish and for that reason explanation will be held in the same language)

Sea p_{o} el precio original del computador portatil, el nuevo precio es:

p_{1} =\left(\frac{100\,\% + 25\,\%}{100\,\%} \right)\cdot p_{o}

p_{1} = 1.25\cdot p_{o}

Si p_{2} = p_{o}, entonces el porcentaje requerido para recuperar el precio original es:

r = \left(1-\frac{p_{2}}{p_{1}} \right)\times 100\,\%

r = \left(1-\frac{p_{o}}{1.25\cdot p_{o}} \right)\times 100\,\%

r = \left(1-\frac{1}{1.25} \right)\times 100\,\%

r = 20\,\%

Se requiere un 20 por ciento de descuento.
