Answer:

40.4%

Step-by-step explanation:

Given data

Initial depth= 5feet

Final depth= 5-3.2+6.6= 8.4feet

Hence the percent change

% change= FInal-initial/final*100

% change= 8.4-5/8.4*100

% change= 3.4/8.4*100

% change= 0.404*100

% change=40.4%

Hence the percent change is 40.4%

Percentage change between two measurement is the proportion of

change between the measurement expressed as a percentage.

The percentage change in the river depth in in 1848 is 106.25%

Reasons:

The given parameters are;

The depth of the river in the year 1846 = 5 feet

In the year 1847, the depth = 3.2 feet

In 1848 the depth = 6.6 feet

[tex]\displaystyle Percentage \ change = \mathbf{ \frac{Current \ depth - Previous \ depth}{Previous \ depth}}[/tex]

Which gives;

[tex]\displaystyle Percentage \ change = \frac{6.6 -3.2}{3.2} \times 100 = \mathbf{106.25 \%}[/tex]

The percentage change in the river depth in the current period = 106.25%
