a container and a bottle had a total of2015 liters of oil in them. When 0.18 liter of oil was poured from the container into the bottle the container had 4 times as much oil as he bottle. How many liters of oil were in the container at first?

1612.18 liters of oil were in the container first

Step-by-step explanation:

Volume of oil in the container=x

Total volume of oil in the bottle and the container=2015 L

Volume of the oil in the bottle=2015-x

When 0.18L oil was poured from the container to the bottle

New volume in the container=x-0.18

New volume in the bottle=2015-x+0.18

New volume in the container is 4 times the oil that was in the bottle

Hence x-0.18=4 (2015-x+0.18)

x-0.18=8060-4x+0.72

x=1612.18
