Answer:
$20.80
Explanation:
First, we will take the large necklace and one small necklace and add the costs together. 6.10 plus 4.90 equals 11. Now, we will take the remaining 2 small necklaces and add them together. 4.90 plus 4.90 equals 9.80. Next, we take our two totals and add them together. 11 plus 9.80 equals 20.80. Therefore, he earned $20.80 for selling the necklaces.
