cuanto pagaríamos por un libro cuyo precio es de $25 si le aplicamos un descuento del 25% cuanto dinero ahorramos

kotegsom [21]

Tenemos precio de lista de $25 para el libro.

Si aplicamos un descuento del 25%, este descuento representa:

$D=(\frac{25}{100})\cdot25=0.25\cdot25=6.25$

Ahorramos $6.25.

El precio que pagamos el libro es $18.75.

$P=L-D=25-6.25=18.75$

If x varies directly with y and x = 6 when y = 15, find x when y= 20.

Kaylis [27]

Answer:

Step-by-step explanation:

Varies directly think y=kx

Varies indirectly think y=k/x

We have first option so y=kx

x=6 and y=15 means we have 15=k(6)

So k=15/6 or reducing gives=5/2

So we just found our constant of proportionality, this number never changes. It stays the same no matter what x or y they give you...

So the equation is y=5/2 *x

Now what is x if y=20

Plug in 20=5/2 *x

So x=20*2/5=40/5=8
