Answer:

Money required $=\$ 8$

Step-by-step explanation:

Nina already owns 2 necklaces and she wants to have total 6 necklaces.

Number of necklaces she needs more $=6-2=4$

Price of $1\ necklaces=\$2$

Money required to buy $4\ necklaces$ $=cost\ of\ 1\ necklace\times number\ of\ necklaces$

$x=2\times 4\\x=\$ 8$
