Question

Nayeli went shopping for a new pair of sneakers. sales tax where she lives is 3.5%. if the price of the pair of sneakers is pp dollars and cents, which expression does not represent the total price plus tax?

Answer 1

To calculate the total price of the sneakers including tax, convert the sales tax rate to a decimal and multiply by the price, then add this to the original price. An incorrect expression would not follow this procedure correctly.

Step-by-step explanation:

The question pertains to the calculation of the total cost of a pair of sneakers, including sales tax. The expression that does not represent the total price plus tax should be identified. This can be achieved by understanding how to calculate sales tax on a purchase.

First, we convert the sales tax rate from a percent to a decimal. For a 3.5% sales tax, this would be 0.035. Next, we calculate the amount of sales tax on the item by multiplying the price (represented as pp dollars) by the sales tax rate. The formula for the amount of sales tax would be pp × 0.035. Finally, we add this amount to the original price to find the total cost.

To find incorrect expressions for the total price plus tax, we must look for expressions that do not follow this procedure. For instance, an expression that multiplies the original price by the tax rate without first converting the percentage to a decimal, or an expression that subtracts the tax amount instead of adds it, would be incorrect.
