Answer

Answer:

C. The change in Jessenia's money over the 8 weeks is $- 40$.

Explanation:

Step1: Analyze option A

The cost of each treat is $5$, not $40$. So option A is wrong.

Step2: Analyze option B

The equation $-5\times8=-40$ represents the total change in money (spending), not her current amount of money. We don't know her initial amount. So option B is wrong.

Step3: Analyze option C

Since she spends $5$ each week (negative sign for spending) for 8 weeks, $-5\times8$ gives the total change in her money (total amount she has spent). So $-40$ is the change in her money over 8 weeks. Option C is correct.

Step4: Analyze option D

The number of weeks is 8, not $-40$. So option D is wrong.
