(8pply Greeting Cards Mei paid \( \$ 15.75 \) for \( 6 \) greeting cards. Some of the cards cost \( \$ 2.50 \) each, and some cost \( \$ 3.25 \) each. Let \( x \) represent the number of cards that cost \( \$ 2.50 \) each, and \( y \) represent the number of cards that cost \( \$ 3.25 \) each. This situation can be represented by the system \( x + y = 6 \) and \( 2.5 x + 3.25 y = 15.75 \) . How many of each type of card did Mei purchase?
