Answer 1

Answer:

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

Step-by-step explanation:

Let $x$ 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,

$x-\frac{50}{100}x=2695\\\\\frac{50}{100}x=2695\\\\\frac{x}{2} =2695\\\\x=2(2695)$

$x=5390$ gallons

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