The answer that you are looking for is
90+9+0.1+0.02+0.004
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.
9 × 16 = 144 the answer is 144
