Question

The function f(x) = 7x + 1 models the fly population in a controlled experiment after x days. According to the model, after how many days will there be 2,401 flies?

a) After 400 days
b) After 300 days
c) After 200 days
d) After 100 days

Answer 1

After approximately 342.86 days, there will be 2,401 flies.

Step-by-step explanation:

The function f(x) = 7x + 1 models the fly population in a controlled experiment after x days.

We are given that the number of flies is 2,401. We need to find the value of x when f(x) = 2,401.

7x + 1 = 2,401

Subtracting 1 from both sides:

7x = 2,400

Dividing both sides by 7:

x = 342.86 approximately

Therefore, after approximately 342.86 days, there will be 2,401 flies.
