Notice that there will be a 1 as without it it'll simply be ab

Notice that it doesn't match with the upper one... so we'll change the signs

Answer:
30396 fish.
Step-by-step explanation:
We are in 2020, that is, 15 years have passed since 2005, to calculate the population it would be:
The first year there would be 48,000, then each year it decreases by 3%, that is, the first one was like this:
48000 - 48000 * 0.03
That is to say:
48000 * (1 - 0.03)
Now, depending on the year number it would be:
48000 * (1-0.03) ^ n
But how were 15 years n = 15, then:
48000 * (1-0.03) ^ 15 = 30396.057
The fish population would be 30396 fish.
If they plan to start the test before lunch, then they should start at 10:10
First of all we are going to take $7.25 and multiply it by 3 here is the math
7.25 x 3 = 21.75
so this means he makes 21.75 dollars a day.
since there are 365 days a year. Now i'm not saying he worked every single day but the question does not say other wise
so we would take 21.75 and multiply it by 365 heres the math
21.75 x 365 = 7,938.75
this means he makes 7,938.75 dollars a year!!
your welcome
merry christmas
