🔢 Estimating Total Cost: Round each item's price to the nearest whole number or convenient fraction (e.g., nearest dollar or 50 cents). 
 ➕ Addition: Add the rounded prices together to get an estimated total. This gives you a quick idea of the final cost.
 🧾 Sales Tax: Calculate sales tax (if applicable) by multiplying the estimated total by the sales tax rate (expressed as a decimal). For example, if the sales tax rate is 6%, multiply by 0.06.
 💯 Final Estimate: Add the estimated sales tax to the estimated total to get the final estimated cost.
 💡 Tip: When calculating sales tax, round the tax amount to the nearest cent.
 📝 Formula Summary:
 
 Estimated Total = Sum of Rounded Prices
 Estimated Sales Tax = Estimated Total $	imes$ Sales Tax Rate
 Final Estimated Cost = Estimated Total + Estimated Sales Tax
