I will give brainliest to the best answer to this question: Each year, the Department of Water Works measures the chloride conce
Maslowich

Answer:

The total change that will likely occur in 2 years is =-3\frac{2}{3} mg/L        

Step-by-step explanation:

Given : The first year, they found the chloride concentration changed by -1\frac{3}{5} mg/L .

It is estimated that the chloride concentration will change -2\frac{1}{15} mg/L the next year.

To find : What is the total change that will likely occur in 2 years?

Solution :

The chloride concentration changed by -1\frac{3}{5}=-\farc{8}{5} mg/L in first year.

The chloride concentration will change -2\frac{1}{15}=-\frac{31}{15} mg/L the next year.

The total change that will likely occur in 2 years is

=-\frac{8}{5}+(-\frac{31}{15})

=\frac{-24-31}{15}

=\frac{-55}{15}

=\frac{-11}{3}

In a mixed fraction - =-3\frac{2}{3} mg/L
