Lydia needs to buy both lanterns and streamers for a party, and she has a maximum budget of $15 for these decorations. Each lantern costs $7, and each pack of streamers costs $5. The following graph shows the solution set for the inequality that represents this situation, where x is the number of lanterns and y is the number of streamers Lydia can purchase.

Which description correctly interprets the solution set for this situation?

The solution set for this situation includes only one answer. Since she can't buy a fractional or negative number of lanterns or packs of streamers, the only solution for the situation is to purchase one of each item.

The solution set includes multiple answers. Since she can't buy a fractional or negative number of lanterns or packs of streamers, the only ordered pairs that are solutions for the situation must have whole number coordinates.

The solution set includes infinitely many answers. She can buy any number of lanterns and packs of streamers that are represented by the shaded region but not the line in the graph.
