Valeria dice que si a una cantidad se le hace un recargo del 300% entonces, debe pagarse el triple de esa cantidad. Silvana le dice que no, que se debe pagar el cuadruple. ¿cuál de las dos tiene razón?

Talia took the bus from her home to the bank and then walked back to her home along the same route. the bus traveled at an average speed of 40 km/h and she walked at an average speed of 5 km/h. to determine the time, x, that it took talia to walk home, she used the equation 40(0.9 – x) = 5x. the time of trip 2 is hours. the distance of trip 1 is km.
