Answer: The equation to find the number of cards could be: c = 300 + 17d, where c equals the total number of cards and d represents the number of days.
The 300 value is the starting amount of cards that Rudy has.
The 17 represents the number of cards that he is getting per day. It started at 15 because that is the amount in a pack of cards. However, he trades one to his brother and gets 3 in return.
15 - 1 + 3 = 17 extra cards per day
All you need to do is add up all the sides to find the perimeter.
300*2=600+450+650=1700m
Final answer: 1700m
