Answer:
[tex]x = \frac{1}{2}[/tex]
Step-by-step explanation:
The ratio of gallons used for one shower is obtained by dividing the total of gallons by the number of showers per day:
[tex]n = \frac{17\,galllons}{2\,\frac{showers}{day} }[/tex]
[tex]n = 8.5\,\frac{gallons}{shower}[/tex]
The ratio of gallons used for one shower to total gallons used is:
[tex]x =\frac{8.5\,gallons}{17\,gallons}[/tex]
[tex]x = \frac{1}{2}[/tex]
