Answer: Let's call the original price of the bracelet "P". We can set up an equation based on the given information:
P + 0.72 = 1.06P
The left side of the equation represents the total amount that Casey paid for the bracelet and sales tax. The right side of the equation represents the original price of the bracelet plus the 6% sales tax.
To solve for P, we can simplify and solve the equation:
P + 0.72 = 1.06P
Subtract P from both sides:
0.72 = 0.06P
Divide both sides by 0.06:
P = 12
Therefore, the original price of the bracelet before tax was $12.
