Answer:
The correct answer is the number in the note is 80 and the first digit is 8.
Step-by-step explanation:
Dr. Green finds a note from another scientist. It says how many boxes of bug nets they should bring, but there is a smudge over the first digit of the number.
Number of nets that they must bring is 320.
Each box contains 4 nets.
There number of boxes necessary to be brought is given by = 80.
Therefore the missing digit of number the number in the note is 8.

Answer:
a. y = 4,200
b. 9.2%
Step-by-step explanation:
Given the information:
=> the base number of the exponential function is:
100% - 2.4% = 97.6% = 0.976
Let t is quarter
Let y is the population
=> the following shows an exponential decay function to find the quarterly decay rate is:
y (t)= 4,200
b. The population is decreasing by how much percent per quarter?
Let t = 0 we have: y(0) = 4,200
Let t = 1 we have: y(1) = 4,200
=> the decreasing percentage is:
= (y(0) - y(1)) / y(0)*100%
= (4200 - 3811) / 4200 *100%
= 389/4200*100%
= 9.2%
