The answer is 260 have a good day.
I love it when people ask me these questions.
First of all, I find it easiest to write n equation.
3 / 15 x 8 =
Now that we have an equation, we can figure out a solution.
3 / 15 = 5
5 x 8 = 40
So 8 DVD's would cost $40.00.
Answer:
32.4
Step-by-step explanation:
prior + 8.1 = 40.5 . . . . . . seems to model the problem statement
prior = 32.4 . . . . . . . subtract 8.1 from both sides
Prior to the increase the percent was 32.4.

<em>Comment on the problem statement</em>
When you're talking about a percentage increase in a percentage, it is almost never clear whether you're talking about the percentage of the underlying number, or the percentage of the percentage.
Here, we assume the 8.1 is a percentage of working students, not a percentage of the percentage of workings students. If you actually intend the latter, the percentage before the increase was about 37.465%.
Answer:
Step-by-step explanation:
<u>According to the model, the equation is:</u>
Based on the equation, the initial number of insects is 3450
<u>If b = 1.75, daily growth rate is:</u>
<u>If we get P(4) = 55200, find the value of b:</u>
- 55200 = 3450*b⁴
- b⁴ = 55200/3450
- b⁴ = 16
- b⁴ = 2⁴
- b = 2
