Answer 2

Answer: option A is the correct answer.

Step-by-step explanation:

Let p represent the number of years for which his parents bought him rare Pokémon cards.

His parents buy him 3 rare cards every year on his birthday. This means that in p years, he would be getting 3p rare cards from his parents.

He currently has 42 cards in his collection. This means that the number of cards that he would have in his collection in p years is

3p + 42

Therefore, the time it will take him to collect 78 Pokémon cards would be

3p + 42 = 78
