Explanation:

Answer 2

The percentage decrease in the depth is 45%

Explanation:

January, lake depth = 1086 feet

august, lake depth = 597.3 feet

The decrease in depth = 1086 - 597.3

= 488.7 feet

Percentage decrease = decrease over January lake depth multiply by 100%

% decrease = (488.7/1086)*100%

=0.45*100%

= 45%
