Final answer:
Jersey started with an amount of savings s. After spending half and earning $25 from chores, she had $165 left. Solving for s, we find that she initially had $280, which is not listed in the options provided.
Step-by-step explanation:
We need to figure out the initial amount of money Jersey had saved before she spent and earned more. Let's call the initial amount s.
Here's how we can write down what happened to Jersey's money:
- Jersey spent 1/2 of her savings on clothes, so she was left with s/2.
- Then she added $25 to her remaining savings by doing chores.
- After these transactions, Jersey has $165 in total.
Using this information, we can write the equation:
s/2 + 25 = 165
Now, let's solve for s:
s/2 = 165 - 25
s/2 = 140
s = 140 * 2
s = 280
So, Jersey had saved $280 in the beginning. However, since this option is not listed, it seems there might have been an error in the question or the provided options. The correct answer (s = $280) does not match any of the options A) $70 B) $80 C) $90 D) $100.
