Jenny bought scrapbooking supplies for $111.00. She paid $7.77 in sales tax. What was the sales tax rate on the supplies? If necessary, round your answer to the nearest tenth.
To find the sales tax rate on the supplies, you need to divide the amount of sales tax paid by the total cost of the supplies, and then multiply by 100 to convert it to a percentage.
In this case, the amount of sales tax paid is $7.77, and the total cost of the supplies is $111.00.
To find the sales tax rate:
Sales tax rate = (Sales tax paid / Total cost of supplies) * 100.
Plugging in the values, we get:
Sales tax rate = (7.77 / 111.00) * 100.
Calculating the fraction first:
Sales tax rate = 0.0700 * 100.
Finally, we multiply to convert it to a percentage:
Sales tax rate = 7.00%.
Therefore, the sales tax rate on the supplies is 7.00%.
