Answer 2

Answer:

• $7

----------------------------

Each bracelet cost $5 and necklace costs x.

The total for 3 of each is:

• 40 - 4 = 36

Set equation and solve for x:

• 3(5 + x) = 36                      Divide both sides by 3
• 5 + x = 12                           Subtract 5 from both sides
• x = 7
