Final answer:
Jane will earn a total of $20.70 from selling 3 large necklaces at $5.40 each and 1 small necklace at $4.50.
Step-by-step explanation:
To calculate the total earnings of Jane, we need to multiply the selling price of the large necklace which is $5.40, by the amount she sold, namely 3 necklaces. Then multiply the selling price of the small necklace, $4.50 by the amount she sold, namely 1 necklace. Finally, add these two amounts together to get the total earnings.
The calculation would be (3*$5.40) + (1*$4.50) = $16.20 + $4.50 = $20.70.
So, Jane would earn $20.70 from selling 3 large necklaces and 1 small necklace.
