Answer:
640 foxes
Step-by-step explanation:
The actual formula is
Now that we have the real formula we would need to find out how many 13 year periods exist in the 26 years that are being used in the question. We calculate this by simply dividing 26 by 13.
26 / 13 = 2 periods
Therefore, now that we know there are 2 periods of 13 years in the 26-year span, we plug this value into the formula and solve for y...
Finally, we can see that there should be 640 foxes after 26 years.
