Answer 2

Answer:

She bought 3 necklace and bracelet sets

If i can be brainliest that would be great

Step-by-step explanation:

Each set contains a necklace and a bracelet

∵ Each necklace cost $9.99

∵ Each bracelet cost $7.99

∴ The cost of one set = (9.99 + 7.99)

∵ She spent on them $53.94

- Add the cost of a necklace and the cost of a bracelet and

 multiply the sum by x  and then equate the product by 53.94

∴ (9.99 + 7.99)x = 53.94

∴ 17.98 x = 53.94

- Divide both sides by 17.98

∴ x = 3
