Answer:

El total que la señora Rina pagó por sus frutas, en términos de b, es:

  • <u>5b - 7</u>

Step-by-step explanation:

Para resolver este ejercicio, primero sacaremos las variable que nos brindan:

  • Costo de la pera = b
  • Costo de la manzana = b - 7 (esto se debe a que la manzana cuesta 7 pesos menos que la pera, tal como dice el enunciado).

Ahora, nos centraremos en la compra realizada por la señora Rina, donde se menciona que:

  • <em>Compra de la señora Rina = 4 peras + 1 manzana</em>

Ahora, como si esto fuera una ecuación, vamos a reemplazar las manzanas y las peras por las variables que tenemos de su costo:

  • Compra de la señora Rina = 4b + b - 7

Y procedemos a operar:

  • <u>Compra de la señora Rina = 5b - 7</u> (sumando 4b + b)

Por lo tanto, <u><em>la compra de la señora Rina, en términos de b, le ha costado 5b - 7</em></u>.
