Christina used cups of shampoo to wash her hair 13 days how many cups of shampoo did she use to wash her hair one day

Answer 1

To determine how many cups of shampoo Christina used to wash her hair in one day, you need the total number of cups she used over the 13 days. If you provide that number, I can help you calculate the average cups of shampoo she used per day.

If, for example, she used a total of \( x \) cups of shampoo over 13 days, then the number of cups she used in one day would be:

\[ \text{Cups per day} = \frac{x}{13} \]

Please provide the total number of cups used!
