Solutions to the Questions: a. ¿La representación de los datos en un gráfico cartesiano ayuda a entenderlos mejor? ¿Por qué? Answer: Yes, representing the data on a Cartesian graph would help to understand the trend more clearly. A graph can visually display the fluctuations and trends in sales over the years, making it easier to identify patterns such as increases, decreases, and periods of stability, which might not be as obvious when looking at raw numerical data alone. b.

Connect the points to observe the trend. c. Analicen la evolución de las ventas a partir del gráfico que obtuvieron.
