Answer:
800 artículos.
Step-by-step explanation:
Sea x = la cantidad de artículos vendidos
De la pregunta,
Precio de costo = 60 x + 4000
Venta (precio de venta) = 80x
También nos dieron ganancias como S12000
Para determinar la ganancia
Precio de venta: precio de costo = beneficio (cuando el precio de venta es más alto que el precio de costo)
Por lo tanto,
12,000 = 80x - (60x + 4000)
12,000 = 80x - 60x - 4000
Recolectando términos similares
12,000 + 4,000 = 80x - 60x
16,000 = 20x
x = 16,000 / 20
x = 800
Por lo tanto, la cantidad de artículos que se venderán si desea obtener una ganancia de S12,000 es de 800 artículos.

Answer: The height of the building is 50.75 feet.
Step-by-step explanation:
The ratio between the height of the object and the casted shadow must be equal for all the objects, as the angle at which the source if light impacts them is the same.
For the person, we know that it is 5.8ft tall, and the shadow is 3.2ft long.
The ratio will be: 5.8ft/3.2ft = 1.8125
Now, if H is the height of the building, and the shadow that the building casts is 28ft, we must have:
H/28ft = 1.8125
Now we can solve this for H.
H = 1.8125*28ft = 50.75 ft
Then the height of the building is 50.75 feet.

Answer:
Step-by-step explanation:
(-3/4)x + 9 = (-1/2)x + 8
9 - 8 = (-1/2)x + (3/4)x
1 = (1/4)x
x = 4
y = (-3/4)4 + 9
y = -3 + 9
y = 6
