A pack of cinnamon scented pencils sells for seven dollars what is the sales tax rate if the total cost of the pencils is $7.56
7 + r*7 = 7.56.
7r = 0.56,
r = 0.08 = 8%.
8% because 7 x 8 = 56 (so, 7 x 8% = 7.56).
Hope this helps :)
Khan Academy has a lot of video on solving Tax-related Problems!!
To determine the sales tax rate, we need to find the difference between the total cost and the original price of the pencils.
The original price of the pencils is $7.00, and the total cost is $7.56. The difference between the two is $7.56 - $7.00 = $0.56.
To find the sales tax rate, we can divide this difference by the original price of the pencils and multiply by 100 to express it as a percentage.
Sales tax rate = (Difference / Original price) * 100
Sales tax rate = ($0.56 / $7.00) * 100
Sales tax rate ≈ 8%
Therefore, the sales tax rate for the pack of cinnamon-scented pencils is approximately 8%.
