Q. Jin went shopping for a new camera. Sales tax where he lives is 8% 8 \% . If the price of the camera is p p dollars and cents, which expression represents the total price plus tax?\newline0.08p 0.08 p \newline1.008p 1.008 p \newline1.08p 1.08 p \newline8p 8 p
  1. Understand total price calculation: First, we need to understand that the total price including tax is the original price plus the tax on that price. The tax is calculated as a percentage of the original price. In this case, the sales tax is 8%8\%.
  2. Calculate tax rate: To find the total price including tax, we multiply the original price by 11 plus the tax rate (expressed as a decimal). The tax rate is 8%8\%, which is 0.080.08 as a decimal.
  3. Find total price with tax: The expression to represent the total price including tax is therefore the original price pp multiplied by 11 plus the tax rate: p×(1+0.08)p \times (1 + 0.08).
  4. Simplify expression: Simplifying the expression, we get: p×1.08p \times 1.08.
