Answer:
The equation that models the cost of each bracelet is
. Cost of each bracelet is $7.
Step-by-step explanation:
Let the cost of each bracelet is defined by the variable x.
Cost of 9 bracelet is 9x. The shipping cost is $9. Therefore the total cost of 9 bracelets, including shipping is
![\text{Total Cost}=9x+9](https://tex.z-dn.net/?f=%5Ctext%7BTotal%20Cost%7D%3D9x%2B9)
The total cost for 9 bracelets, including shipping is $72.
![72=9x+9](https://tex.z-dn.net/?f=72%3D9x%2B9)
Subtract 9 from both sides
![72-9=9x+9-9](https://tex.z-dn.net/?f=72-9%3D9x%2B9-9)
![63=9x](https://tex.z-dn.net/?f=63%3D9x)
Divide both sides by 9.
![7=x](https://tex.z-dn.net/?f=7%3Dx)
Therefore the cost of each bracelet without shipping changes is $7.
