Question

an oil spill washed up on the coast and coated a total of 983 birds with oil. so far, a team of volunteers has cleaned 530 birds. how many more birds do the volunteers need to clean?

Explanation:

Step1: Identify total and cleaned birds

The total number of oil - coated birds is 983 and the number of birds already cleaned is 530.

Step2: Calculate remaining birds

We subtract the number of cleaned birds from the total number of oil - coated birds. Let $x$ be the number of birds yet to be cleaned. So $x = 983−530$.
$x=453$

Answer:

453
