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
