Un capital es impuesto al 12% anual y un segundo capital al 9% anual la diferencia de dichos capitales es de S/.1350. Si el interés trimestral que produce el primero es al interés semestral que produce el segundo como 5 es a 3. ¿Cuál es el mayor capital? A) S/.2250 B) S/.3000 C) S/.4100
D) S/.4750 E) S/5200

C

Step-by-step explanation:

the direct variation says that:

then the equation is of the form is given by:

            where k is the constant variation.

from the given table:

consider any value of x and m(x)=y

x = 2 and m(x)=y = 3

substitute these value in [1]; we have;

divide both sides by 2 we get;

⇒

check:

put x = -1 and m(x) = -1.5

substitute in the equation:

-1.5 = -1.5                   true

therefore, the function m(x) represents a direct variation
