Luke paid $12.69 for 3 greeting cards. each card cost the same amount,
c. which equation and solution represents this situation?

Here, c represents the cost of one greeting cards,

Since, each card costs same,

Thus, the cost of 3 greeting cards = 3 × the cost of one greeting cards

= 3 × c

= 3c

According to the question,

The cost of 3 greeting cards = $ 12.69

⇒ 3c = 12.69

Which is the required equation that represents the given situation,

After solving this,

We get,

c = 4.32,

Thus, the cost of one card is $ 4.32.

Which is the required solution.
