Mel 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
2.5x + 3.25y = 15.75. How many
of each type of card did Mei
purchase?
