To determine how many rolls of paper towels Cady will use in 8 weeks, we can multiply the amount of a roll she uses each week by 8.
Let's denote the amount of a roll of paper towels that Cady uses each week as \( x \).
The total amount used in 8 weeks will be \( 8x \).
Since we don't have the specific amount that Cady uses each week, I'll assume that the amount of a roll she uses each week is represented by a fraction that results in one of the options presented (A, B, C, D).
If we take the options into consideration:
To get option B (1 8/9 rolls): This means she would use approximately \( \frac{1 + \frac{8}{9}}{8} \), leading to: \[ \frac{17}{9 \times 8} = \frac{17}{72} \text{ rolls per week, which will sum up to } 1 \text{ roll in 8 weeks} \]
Similarly for the other numbers:
- If she uses \( 9 \) rolls in total, she would use: \[ \frac{1}{8} \text{ rolls per week} = 8 \text{ rolls} = \text{ no options listed} \]
Continuing in this pattern will lead to a contradiction since no specific number was given.
In the absence of knowing specifically how much Cady uses in a week, I would need additional information to arrive at any of the given options.
If you have the specific fraction Cady uses each week, please provide that, and I'd be more than happy to help you with the calculation!
