Rajani went shopping for a new pair of sneakers. Sales tax where she lives is 10%. What number should she multiply the price of the pair of sneakers by to find the total plus tax in one step?

Answer 1

To find the total price including sales tax in one step, Rajani should multiply the price of the sneakers by \( 1 + \text{sales tax rate} \).

Since the sales tax rate where she lives is 10%, this can be expressed as 0.10 in decimal form. Therefore, the calculation would be:

\[ 1 + 0.10 = 1.10 \]

So, Rajani should multiply the price of the pair of sneakers by \( 1.10 \) to find the total price including tax.
