Explanation:
Hans earns $5.70 for each large necklace he sells and $4.20 for each small necklace he sells. To find out how much he will earn from selling 1 large necklace and 4 small necklaces, we need to multiply the price of each necklace by the number of necklaces sold and then add the results.
For the 1 large necklace, Hans earns:
1 x $5.70 = $5.70
For the 4 small necklaces, Hans earns:
4 x $4.20 = $16.80
To find the total amount that Hans earns, we need to add these two amounts:
$5.70 + $16.80 = $22.50
Therefore, Hans will earn $22.50 from selling 1 large necklace and 4 small necklaces.
