i have a question i don't quite understand, i am preparing for a exam.

A 100-gallon mixture of citrus extract and water is 3% citrus extract, and it needs to be diluted. The function f(x)=3/100+x represents the percentrage (in decimal form) of the miture that is citrus extract when x gallons of water are added.
Find the domain of f(x). Then, find the percentage of citrus extract in the mixture after 50 gallons of water are added to it.
