Answer:

Necklace cost $144 and bracelet cost $48

Step-by-step explanation:

call x is the price of necklace, y is the price of bracelet

because necklace cost 3 time as much as the bracelet

=> 3x = y

A necklace and a bracelet cost $192

=> x + y = 192

=>set of equations

3x = y and x+y = 192

x= 3y and 3y + y = 192

=> y = 48 and x = 3 . 48 = 144
