Jenny bought scrapbooking supplies for $123.00. She paid $8.61 in sales tax. What was the sales tax rate on the supplies? If necessary, round your answer to the nearest tenth.

8.61/123.00 = 0.07 = 7%

To determine the sales tax rate on the supplies, we can divide the amount of tax paid by the total cost of the supplies.

Sales tax rate = (Tax paid / Total cost) * 100

Given:
Tax paid = $8.61
Total cost = $123.00

Sales tax rate = (8.61 / 123.00) * 100
Sales tax rate ≈ 0.0701 * 100
Sales tax rate ≈ 7.01%

Therefore, the sales tax rate on the supplies was approximately 7.01%.

To find the sales tax rate on the supplies, we can divide the amount of sales tax paid by the total cost of the supplies and multiply by 100 to get the percentage.

Step 1: Determine the sales tax rate
Sales tax rate = (Sales tax paid / Total cost of supplies) * 100

Step 2: Calculate using the given values
Sales tax rate = ($8.61 / $123.00) * 100

Step 3: Simplify the expression
Sales tax rate = (0.07) * 100

Step 4: Calculate the result
Sales tax rate = 7.0

Therefore, the sales tax rate on the supplies is 7.0%.
