Answer:

the amount of interest she pays is 400 dollars

Step-by-step explanation:

Since 5 percent of 2000 is 100

I multiplied 100 by 4 because she waits 4 year to pay it off

which equals 400

(this is extra in case I misunderstood the question lol)

<em>I added 400 to the initial cost of 2000 </em>

<em>which is 2400</em>

La edad de juan es un año menos que la tercera parte de la edad de la madre. si dentro de 5 años, la edad de la madre sera 10 añ
koban [17]

Usando un sistema de ecuaciones, se encuentra que Juan tiene 12 años e su madre tiene 39 años.

<h3>¿Qué es un sistema de ecuaciones?</h3>

Un sistema de ecuaciones es cuando dos o más variables están relacionadas y las ecuaciones se construyen para encontrar los valores de cada variable.

En este problema, las variables son:

  • Variable x: Edad de Juan.
  • Variable y: Edad de su madre.

La edad de juan es un año menos que la tercera parte de la edad de la madre, por eso:

x = \frac{y}{3} - 1

Dentro de 5 años, la edad de la madre sera 10 años mas que el doble de juan, por eso:

y + 5 = 2(x + 5) + 10

y + 5 = 2x + 20

Como x = \frac{y}{3} - 1:

y + 5 = \frac{2y}{3} + 18

3y + 15 = 2y + 54

y = 39

x = \frac{y}{3} - 1 = \frac{39}{3} - 1 = 13 - 1 = 12

Juan tiene 12 años e su madre tiene 39 años.
