Respuesta :

Answer:

[tex]- 2\frac{1}{2}[/tex] inches

Step-by-step explanation:

The water level at Lake Penny changed [tex] - 1\frac{1}{10} = - 1.1 [/tex] inches

Again, in the next year, it is predicted to change another [tex] - 1\frac{2}{5} = - 1.4 [/tex] inches

Therefore, the total change that will likely occur in 2 years is (- 1.1 - 1.4 ) = - 2.5 inches = [tex]- 2\frac{1}{2}[/tex] inches. (Answer)
