Johan - 3 × Kenney ( 3k )
Lily - 3k - 200
Kenny - k

3k + ( 3k - 200 ) + k = 1550
3k + 3k - 200 + k = 1550
7k - 200 = 1550
7k = 1550 + 200
7k = 1750
k = 1750 ÷ 7
   = 250

Johan - 3 × 250 = 750
Kenny - 250
Lily - 750 - 200 = 550

K = 350 J = 3K = 3 x 350 = 1050 L = K - 200 = 150
K = 350
J = 3K = 3 x 350 = 1050
L = K - 200 = 150
