Answer

Answer:

A. $50 - 2.5x=y$ $40 - 2x=y$

Explanation:

Step1: Analizar el caso de Kaisorn

Kaisorn deposita $50$ dólares y cada viaje cuesta $2.5$ dólares. El saldo $y$ en su cuenta es el depósito inicial menos el costo total de los viajes. El costo total de $x$ viajes es $2.5x$, entonces la ecuación es $y = 50-2.5x$.

Step2: Analizar el caso de Thom

Thom deposita $40$ dólares y cada viaje cuesta $2$ dólares. El saldo $y$ en su cuenta es el depósito inicial menos el costo total de los viajes. El costo total de $x$ viajes es $2x$, entonces la ecuación es $y = 40 - 2x$.
