Because
P=a+b+c
a+b+c=P
b=P-a-c

Al precio de p dólares por unidad, se venden x unidades de cierto artículo al mes en el mercado con p=50-0.5x ¿Cuántas unidades

Ray Of Light [21]

Answer:

Se debe vender un mínimo mensual de 40 artículos para tener un ingreso mínimo de 1.200 dólares.

Step-by-step explanation:

De acuerdo con el enunciado, $x$ es la cantidad mínima de artículos a un precio de $p$ . Además, los ingresos totales deben ser de un mínimo de 1200. En consecuencia, tenemos el siguiente sistema de ecuaciones:

$x \cdot p = 1200$ (1)

$p = 50-0.5\cdot x$ (2)

Aplicando (2) en (1), tenemos la siguiente ecuación polinómica:

$x\cdot (50-0.5\cdot x) = 1200$

$50\cdot x -0.5\cdot x^{2} = 1200$

$0.5\cdot x^{2}-50\cdot x +1200 = 0$ (3)

Por la Fórmula de la Cuadrática tenemos las raíces del polinomio:

$x_{1} = 60$ , $x_{2} = 40$

De acuerdo con el resultado anterior, se debe vender un mínimo mensual de 40 artículos para tener un ingreso mínimo de 1.200 dólares.

How many groups of 1/2 days are in 1 week? Write a multiplication equation or a division equation to represent the question, the

worty [1.4K]

Answer:

14 groups

Step-by-step explanation:

Given

$Groupings = \frac{1}{2}\ day$

$Duration = 1\ week$

Required

Determine the number of group in the week

To do this, we simply divide the duration by the number half day group.

This gives:

$Group = \frac{Duration}{Groupings}$

$Group = \frac{1\ week}{1/2\ days}$

Convert week to days

$Group = \frac{7\ days}{1/2\ days}$

$Group = \frac{7}{1/2}$

$Group = 7 / \frac{1}{2}$

Convert to multiplication

$Group = 7 * \frac{2}{1}$

$Group = \frac{14}{1}$

$Group = 14$

<em>Hence, there are 14 groups</em>
