What is the original price of the bracelet, before tax?

Answer 1

$0.68

Explanation:

To find the original price of the bracelet, write a proportion. $0.72 is the amount after a 6% tax rate. This means you paid 6% on the original price.

`(0.72)/(y)=(106)/(100)`

Find y by cross multiplying numerator and denominator of each fraction.

0.72(100) = 106y

72 = 106y

0.679 = y

0.68 = y
