Q. Samir went shopping for a new pair of pants. To find the total plus tax, he multiplied the price of the pair of pants by 11.0909 . What percent tax did he pay?\newlineAnswer: % \%
  1. Understand Problem: Understand the problem and identify what is given and what needs to be found.\newlineSamir multiplied the price of the pants by 1.091.09 to find the total cost including tax. The “1”\text{“}1\text{”} in 1.091.09 represents the original price of the pants, and the “0.09”\text{“}0.09\text{”} represents the tax rate. We need to find the percentage that the tax rate represents.
  2. Express Tax Rate: Express the tax rate as a percentage.\newlineSince the tax is represented by the decimal 0.090.09 (which is part of the 1.091.09 multiplier), we convert it to a percentage by multiplying by 100100.\newlineCalculation: 0.09×100=9%0.09 \times 100 = 9\%
  3. Check Calculation: Check the calculation for any mathematical errors.\newlineRe-checking the calculation: 0.09×100=90.09 \times 100 = 9. No errors found.
