Juan y sofi compraron 3kg de manzanas pagaron 65 pesos, cuanto pagaron por 1,5Kg y 10kg?

Step-by-s⭐Explicación paso a paso:

Aplicamos una regla de tres simple directamente proporcional, ya que entre mayor sea la cantidad de kilogramos comprados, mayor será la cantidad de dinero que se debe pagar por las manzanas (y viceversa).

Expresamos:

Kilogramos         Dinero ($)

    3                           20

   15                            x

x= (15 * 20)/3

x = 300/3

x = 100$

tep explanation:

let x be the money she spent so that she can earn the free t-shirt.

since, she already spent $112.49

⇒

also, as per the statement: jennifer must spend $250 or more in order to qualify for a free t-shirt at the store.

then,

we have an inequality i.,e

subtract 112.49 from both sides we get;

therefore, $137. 51 more money does jennifer need to spend so that she can earn the free t-shirt

the answer is 24
