Question

A population of lizards decreases exponentially at a rate of 12.5% per year. What is the equivalent monthly rate to the nearest hundredth of a percent?

a. 0.20%
b. 1.04%
c. 1.11%
d. 1.23%

Answer 1

1.04%

Explanation:

We are given that there is 12.5% decrease in lizards exponentially in 1 year i.e. 12 months.

Therefore, the percentage decrease in lizards per month will be 12.5% divided by 12.

i.e.
`(12.5)/(12)` = 1.0416667%

So, the percentage decrease per month is 1.0416667%

Hence, rounding 1.0416667% to nearest hundredth, we get 1.04%

Answer 2

Answer:1.04%

Explanation:

12.5/12 = 1.04166667

when we round this to the nearest hundredth its 1.04%
