Question

bob and ivan are going on a road trip together. they have a limited budget, so they consider several different routes and calculate the cost of gas for each route. the cost of gas for each route depends on the length of the route. g = the cost of gas r = the length of the route which of the variables is independent and which is dependent? r is the independent variable and g is the dependent variable g is the independent variable and r is the dependent variable

Explanation:

La variable independiente es aquella que se puede controlar o cambiar libremente. En este caso, la longitud de la ruta \( r \) es la variable independiente porque Bob e Ivan pueden elegir diferentes rutas (es decir, diferentes longitudes \( r \)). La variable dependiente es aquella que depende de la variable independiente. El costo del gas \( g \) depende de la longitud de la ruta \( r \) (ya que se dice que "el costo de gas para cada ruta depende de la longitud de la ruta"), por lo que \( g \) es la variable dependiente.

Answer:

\( r \) is the independent variable and \( g \) is the dependent variable.
