Ivan sells beaded necklaces. Each large necklace sells for $6.10 and each small necklace sells for $4.90. How much will he earn from selling 1 large necklace and 3 small necklaces?

$20.80

Step-by-step 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.
