Elena is considering buying bracelets and necklaces as gifts for her friends. Bracelets cost $3, and
necklaces cost $5. She can spend no more than $30 on the gifts. Elena needs at least 7 gift items.
This graph represents the inequality
3b+5n30, which describes the cost
constraint in this situation.
Let b represent the number of bracelets and n
the number of necklaces.

1. Write an inequality that represents the number of gift items that Elena needs.
2. On the same coordinate plane, graph the solution set to the inequality you wrote.
3. Use the graphs to find at least two possible combinations of bracelets and necklaces Elena could bu
4. Explain how the graphs show that the combination of 2 bracelets and 5 necklaces meet one constraint
