Answer 1

`- 2(1)/(2)` inches

Explanation:

The water level at Lake Penny changed
`- 1(1)/(10) = - 1.1` inches

Again, in the next year, it is predicted to change another
`- 1(2)/(5) = - 1.4` inches

Therefore, the total change that will likely occur in 2 years is (- 1.1 - 1.4 ) = - 2.5 inches =
`- 2(1)/(2)` inches. (Answer)
