Answer:
After 4 hours the container left with 20 gallons of water.
Step-by-step explanation:
The container has 320 gallons of water initially.
It leaks half of its water every hour.
So, after 1 hour the container has [tex]\frac{320}{2}[/tex]= 160 gallons
After 2 hours the container has [tex]\frac{160}{2}[/tex] =80 gallons
After 3 hours the container has [tex]\frac{80}{2}[/tex]= 40 gallons
After 4 hours the container has [tex]\frac{40}{2}[/tex] =20 gallons.
So, after 4 hours the container left with 20 gallons of water.
