Question

29 modeling real life in a four - year period, about 80000 acres of coastal wetlands in the united states are lost each year. what integer represents the total change in coastal wetlands?

Explanation:

Step1: Identify the annual loss

The annual loss of coastal wetlands is 80000 acres. Since it is a loss, we represent it as - 80000 (negative integer for decrease).

Step2: Calculate total change over 4 - year period

We multiply the annual loss by the number of years. The formula is total change=annual change×number of years. So, total change = - 80000×4.
-80000×4=-320000

Answer:

• 320000
