A lake initially contains 3000 fish. Suppose that in the absence of predators or other causes of removal, the fish population increases by 6% each month. However, factoring in all causes, 400 fish are lost each month. How many fish will be in the pond after 9 months? (Don't round until the very end.)

Ответ:
Let x = number of months.
Let y = total number of fish in pond.
6% of 3,000 = 180 fish
We can use an equation to help us with this problem.
y = 3,000 + 180x - 400x. Combine like terms.
y = 3,000 - 220x. Plug 9 in for x.
y = 3,000 - 220(9). Solve for y
y = 1,020.
There are 1,020 fish in the pond after 9 months.

So we need to convert 0.75 feet to inches.
0.75 feet = 9 inches
Then we divide 9 by how many hours are in a day: 24
9/24 = 0.375
The raindrop vine can grow up to 0.375 inches per hour.
