Verified step by step guidance1
First, identify the sales tax rate by dividing the sales tax amount by the price of the shoes. Use the formula: \(\text{Sales Tax Rate} = \frac{\text{Sales Tax}}{\text{Price}}\).
Substitute the known values into the formula: \(\text{Sales Tax Rate} = \frac{1.26}{36}\).
Calculate the sales tax rate (you can leave it as a fraction or decimal for now).
Next, use the sales tax rate to find the sales tax on the \$250 pair of shoes by multiplying the rate by 250: \(\(\text{Sales Tax on }\) 250 = \(\text{Sales Tax Rate}\) \(\times\) 250\).
Perform the multiplication to find the sales tax amount on the \$250 shoes (again, you can leave the answer in terms of the rate times 250 without final calculation).
