Answer:
Explanation:
Let S be the number of specimens and W be the number of weeks.
We know that initially Joe starts with 83 specimens, and every week the number of specimens doubles. Therefore, the equation that represents the scenario is:
S = 83 * 2^(W-1)
Here, (W-1) is used to account for the initial number of specimens already given in the problem.
This equation gives the number of specimens S after W weeks, taking into account the doubling of specimens every week.
