Rosa already owns 2 necklaces, and additional necklaces are priced at 1 for a dollar. How
much money does Rosa need to spend on new necklaces in order to own a total of 24
necklaces?
Since you already have 2 necklaces and u want to own a total of 24, you will subtract 2 away from 24 so 24-2=22 and all new necklaces cost 1 dollar so 22x1=22
