Question

jessenia spends $5 on a treat every friday for 8 weeks. the equation below is written to represent the scenario.
-5×8 = -40
which description best explains the meaning of -40 in the equation?
a each treat cost $40.
b jessenia now has -$40.
c the change in jessenias money over the 8 weeks is -40.
d the number of weeks that jessenia spent money was -40.

Explanation:

Step1: Analyze each option

• Option A: Each treat costs $5$, not $40$. So A is wrong.
• Option B: The equation $-5\times8=-40$ represents the total change in money (spending), not the current amount of money (we don't know her initial amount). So B is wrong.
• Option C: Since she spends $5$ each week (a decrease of $5$ per week, represented as $- 5$), over 8 weeks, the total change in her money is $-5\times8=-40$. This is correct.
• Option D: The number of weeks is 8, not $-40$. So D is wrong.

Answer:

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