X=weight of the jug
y=witht of liquid when the jug is full
we suggest this system of equations:
x+y/5=250
x+4y/5=550
we solve this system of equations by equalization method.
x=250-y/5
x=550-4y/5
250-y/5=550-4y/5
least common multiple=5
1250-y=2750-4y
-y+4y=2750-1250
3y=1500
y=1500/3
y=500

x=250-y/5
x=250-500/5
x=250-100
x=150

Answer: weight of the jug = 150grams.

Lunna [17]

Well I think that for this problem we should multiply 3x1/3 which is 1 whole. Sorry if I'm incorrect.
