Question

A study indicated that they wasted 75,900 gallons of water last year and 44,022 gallons of water this year. What is the percent of decrease in the amount of water wasted yearly?

Answer 1

42%

Explanation:

Water wasted last year = 75,900 gallons

Water wasted this year = 44,022 gallons

Percentage decrease in the amount of water wasted yearly = (Water wasted last year - Water wasted this year) / Water wasted last year × 100

= (75,900 - 44,022) / 75,900 × 100

= 31,878 / 75,900 × 100

= 0.42 × 100

= 42%

Percentage decrease in the amount of water wasted yearly is 42%
