Verified step by step guidance1
First, find the sales tax rate by dividing the sales tax amount by the price of the shoes. Use the formula: \(\text{Tax Rate} = \frac{\text{Sales Tax}}{\text{Price}}\).
Substitute the given values into the formula: \(\text{Tax Rate} = \frac{1.26}{36}\).
Calculate the tax rate (you can leave it as a fraction or decimal for now).
Next, use the tax rate to find the sales tax on the \$250 pair of shoes by multiplying the tax rate by 250: \(\(\text{Sales Tax on }\) 250 = \(\text{Tax Rate}\) \(\times\) 250\).
Perform the multiplication to find the sales tax amount for the \$250 shoes (you can leave the final multiplication step for calculation).
