The total cost for 9 bracelets, including shipping was \$72. The shipping charge was \$9. Define your variable and write an equation that models the cost of each bracelet.

We set up a cost function as fixed cost plus total cost. Fixed cost is the shipping charge of \$9. So we have the following cost function where n is the cost of the bracelets:

C(b) = nb + 9

We are given C(9) = 72 and b = 9
9n + 9 = 72

Run this through our equation calculator, and we get n = 7.
The text passage contains a word problem that asks the reader to define a variable and write an equation to model the cost of each bracelet, and it also provides the answer to the equation.
