Final answer:
To determine how many days Jeong attended school, we set up and solved the equation 183 = 2J - 9, which leads to J = 96. Therefore, Jeong attended school for 96 days, and the correct answer is option A.
Step-by-step explanation:
To solve the problem regarding the number of days Heather and Jeong attended school, we can set up an equation. We know that Heather attended school for a total of 183 days which is 9 days less than twice the days Jeong attended. Let's use J to represent the number of days Jeong attended school.
The equation based on the problem statement is:
183 = 2J - 9
To find out how many days Jeong attended, we need to solve for J as follows:
- Add 9 to both sides of the equation: 183 + 9 = 2J – 9 + 9
- This simplifies to: 192 = 2J
- Now divide both sides by 2 to isolate J: 192 / 2 = 2J / 2
- Therefore, J = 96
So, Jeong attended school for 96 days.
The correct answer is option A: 96 days.
