Imagine that you and your friend have decided to save money to buy a new video game that costs R$ 450. Your savings capacity is directly related to the number of days you study mathematics: for each day studied, you can save R$ 5. Your friend, on the other hand, saves R$ 10 per day and studies the same number of days as you. Knowing this, answer:
a) Write an equation that relates the number of days you study and how much you save. Do the same for your friend.
b) In order to reach the necessary amount, how many days would you both need to study together?
c) Use the Cartesian plane to graphically represent the two equations found and identify which point represents the number of days required for both of you to reach the goal.
