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.

finlep [7]

Answer:

Adult tickets sold= 9x4 = 36

Senior tickets sold = 9x3= 27

Child tickets sold = 9 x 1 = 9

Step-by-step explanation:

If the parts for adult tickets changed within the 2 ratios given, we should have equated Ratio further. But here that is not 5e case. So, put both ratios together:

Senior:Adult:Child

3:4:1

Now,

Total number of parts 3+4+1=8

Number of tickets sold per part = 72/8 = 9

Therefore number of

Adult tickets sold= 9x4 = 36

Senior tickets sold = 9x3= 27

Child tickets sold = 9 x 1 = 9

Hope this helps.
