Final answer:
Anya has 2p trading cards, Ben has 6p, and Colin has 3p. The total number of trading cards they have altogether is 11p.
Step-by-step explanation:
The student's question involves solving a simple algebraic problem related to the number of trading cards each person has, and then finding their sum.
Let's denote the number of trading cards Anya has as 2p. According to the problem, Ben has three times as many trading cards as Anya, which means Ben has 3 × 2p = 6p cards. Colin has half as many trading cards as Ben, so Colin has 6p/2 = 3p cards.
To find the total number of trading cards they have altogether, we add Anya's, Ben's, and Colin's cards: 2p + 6p + 3p = 11p.
Therefore, together, Anya, Ben, and Colin have 11p trading cards altogether.
