Sagot :

Answer:

5390 gallons of water was wasted by the city's residents last year.

Step-by-step explanation:

Let [tex]x[/tex] denotes gallons of water wasted by the city's residents last year.

Gallons of water wasted by the city's residents this year = 2695 gallons

This is 50% less than last year.

Therefore,

[tex]x-\frac{50}{100}x=2695\\\\\frac{50}{100}x=2695\\\\\frac{x}{2} =2695\\\\x=2(2695)[/tex]

[tex]x=5390[/tex] gallons

So, 5390 gallons of water was wasted by the city's residents last year.
