Final answer:
To find the cost of each folder, divide the total cost of the folders, $9.05, by the number of folders, which is 6. This calculation results in each folder costing approximately $1.51.
Step-by-step explanation:
To calculate the cost of each folder, we first need to know the total cost of the six folders together. According to the student's information, Sarah bought six folders totaling $9.05. We can find the cost of each folder by dividing this total cost by the number of folders.
To do this, we use the formula:
Cost per folder = Total cost of folders ÷ Number of folders
In this case, it is:
Cost per folder = $9.05 ÷ 6
When we divide $9.05 by 6, we get approximately $1.51 (after rounding to the nearest cent).
So, each folder cost $1.51.
