Question

A researcher is studying the population of

750 birds once a new predator is introduced
into the population. The researcher
determines that the number of birds is
decreasing each year by 3.5%. What is the
multiplier?

Answer 1

• 0.965

Explanation:

Decrease rate is 3.5%, the multiplier is:

• 1 - 3.5% =
• 1 - 0.035 =
• 0.965

The equation to reflect this would be:

• 
  `B(t) = 750*0.965^t`

Here B(t) is the number of birds after t years
