The total cost for 8 bracelets including shipping was$54.the shipping charge was$6.define the variable and write an equation that models the cost of each bracelet.

8 lots of a number plus the $6 shipping gives the total cost of 54
For the sake of conformity, I will say the unknown bracelet cost is x however you can call it whatever you like.
Turning it into an equation:

Now we can work with it properly, and rearrange things more easily. subtracting 6 from both sides:

Now dividing both sides by 8:

Therefore the cost of each bracelet is $6.00
