.

When you say " decreases at a rate of 13% each hour ", you (or the problem) MUST TELL   " 13% of WHAT ? ".

Otherwise, it is not a Math problem, at all.

As I see, there is a flow of so called " quasi "- math problems from an illiterate and unqualified " composer "   at this time . . .

Starts with 5 gallons to decrease 13% each hour, means at some small quantity you need to decide when so little water remains that the container may be called empty.

The container KEEPS 87% each hour.

------this by itself will never become 0.
