atroni [7]

Answer:

$ 30

$ 20

Step-by-step explanation:

Sea el costo fijo xy el costo por km sea y suponiendo que es el mismo para ambos taxis.

De la pregunta obtenemos las dos ecuaciones

$x+8y=190\quad ...(i)$

$x+5y=130\quad ...(ii)$

Aplicando $(i)-(ii)$

$8y-5y=190-130\\\Rightarrow 3y=60\\\Rightarrow y=\dfrac{60}{3}\\\Rightarrow y=20$

Sustituyendo en $(ii)$

$x+5y=130\\\Rightarrow x+5\times 20=130\\\Rightarrow x=130-100\\\Rightarrow x=30$

Entonces, el costo fijo es de $ 30 y el costo por km es de $ 20.
