Answer: $750, $800, $200

Assume that the price of first ring was x
Price of 2nd ring was y
Price of 3rd ring was z

As given in the question, y = x+50
z = y-600 = (x+50)-600
This implies, x+y+z = $1,750
x+x+50+x+50-600 = 1,750
3x = 1750+600-100
x= 2250/3
x = $750
Hence, y =750+50=$800

easier way is to find for the second ring first since both other rings price come from that.y+y-50+y-600=1750 3y-650=1750 3y=1750+650 3y=2400 y=2400/3 y=800 z=800-600=200 x=800-50=750
