Answer:
The sales tax rate of an item that costs $4 is 8%
Step-by-step explanation:
An item costs $4 before tax
The same item costs $4.32 after sales tax.
So the tax rate can be calculated as:
Tax rate = $4.32 - $4 = $0.32
Next, you must divide the tax rate by the original price in order to get the sales tax rate:
Sales tax rate = $0.32/4$ = 0.08
In percentage:
Sales tax rate % = 0.08x100% = 8%
