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?

Note that this is an EXPONENTIAL thing and the monthly rates won't be from dividing by 12, I don't think, based on my first shot at this involving a question with butterflies.
I think the best shots are 1.11 and 1.23 but I NEED to be sure.

0.20%

1.04%

1.11%

1.23%

560

hope this : )

the largest number of the four options is 1.8 x 10-2

you have it in scientific notation.

1.80 x 10-6   = 0.00000180

1.80 x 10-4   = 0.000180 (bigger, or "less small", than the former one)

so

1.8 x 10-2       = 0.0180. as you see. the "less small", or the biggest one of them all.

as you have negative exponent, it means you are dividing 1.8 by 100 (i.e. moving the dot towards left, two times).

if you had positive exponent for the scientific notation, power of tenths, you would be multiplying times 100 (moving the dot towards right) as below:

1.8 x (10)2 = 180

so. if you have negative exponent in scientific notation, move the dot toward left. if it is positive, toward right as many times the exponent tells you.

too hard the other guy did it
