To find the price of one bracelet, you can divide the total cost by the number of bracelets.
The total cost for 10 bracelets is $12.40.
So, the calculation would be:
\[ \text{Price per bracelet} = \frac{\text{Total cost}}{\text{Number of bracelets}} = \frac{12.40}{10} = 1.24 \]
Therefore, the price of one bracelet is $1.24.
