Tanker 3

A gasoline tank weighs 4500kg. If we pump 30% of the gasoline out of the tank, it will weigh 3900kg. How many kilograms does an empty tank weigh?

Correct answer:

m0 =  2500 kg

Step-by-step explanation:

r=100%30%=110030=0.7  m0+b = 4500 kg m0+r b = 3900 kg  br b=45003900 b0.7 b=45003900  0.3b=600  b=0.3600=2000  b=2000  m0=4500b=45002000=2500 kg
