The total cost of the ring including the sales tax is $3,082.70. To find the original price before tax, divide the total cost by 1 plus the tax rate (expressed as a decimal). The tax rate is 6.3%, or 0.063 as a decimal. So, the original price is $3,082.70 / (1 + 0.063) = $3,082.70 / 1.063 ≈ $2,900.
