Por término de temporada varias tiendas liquidan pantalones. Su precio de temporada era de $6. 990. Si quiero comprar tres panta
nlexa [21]

La tienda que ofrezca la mejor oferta por tres pantalones será aquella que tenga el mayor descuento de liquidación posible.

<h3>Análisis contextual de una pregunta incompleta</h3>

En este problema no es posible determinar cuántas tiendas existen ni los descuentos de liquidación (x) correspondientes a cada uno y que todas las tiendas venden los pantalones al mismo precio de temporada (C).

Las condiciones <em>matemáticas</em> de cada variable es:

C = 6990  (1)

x \in [0, 1)   (2)

n = 3   (3)

La fórmula matemática para el precio final (C'), en pesos, es la siguiente:

C' = 3\cdot (6990)\cdot (1-x)   (4)

Consideremos el caso de N tiendas, cada una con un descuento de liquidación por cada pantalón y que ese descuento es aplicable a la compra de tres pantalones, entonces la tienda que ofrezca la mejor oferta por tres pantalones será aquella que tenga el mayor descuento de liquidación posible. \blacksquare

Three brothers share 2 sandwiches equally how much of a sandwich does each brother get?
Valentin [98]
<span><u><em>Answer:</em></u>
Each brother gets </span>\frac{2}{3}<span> of a sandwich

<u><em>Explanation:</em></u>
We know that the total number of sandwiches is 2 and that the number of brothers is 3.

Since we are given that the sandwiches will be divided equally among the three brothers, this means that each will get an equal share.

Therefore, to get the share of each, we will simply <u>divide the number of sandwiches by the number of brother</u>s as follows:
each one will get = </span>\frac{# sandwiches}{# brothers} = \frac{2}{3}<span> of a sandwich

Hope this helps :)</span>
