๐Ÿ“š Quick Study Guide

    ๐Ÿ”ข Estimating Total Cost: Round each item's price to the nearest whole number or convenient fraction (e.g., nearest dollar or 50 cents). โž• Addition: Add the rounded prices together to get an estimated total. This gives you a quick idea of the final cost. ๐Ÿงพ 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. ๐Ÿ’ฏ Final Estimate: Add the estimated sales tax to the estimated total to get the final estimated cost. ๐Ÿ’ก Tip: When calculating sales tax, round the tax amount to the nearest cent. ๐Ÿ“ Formula Summary:
    • Estimated Total = Sum of Rounded Prices
    • Estimated Sales Tax = Estimated Total $\times$ Sales Tax Rate
    • Final Estimated Cost = Estimated Total + Estimated Sales Tax
