Answer:
Explanation:
Yes, there is a proportional relationship between the original price of an item and its price after sales tax.
In general, a proportional relationship between two variables means that the ratio of one variable to the other is constant. In this case, the ratio of the original price of an item to its price after sales tax is constant, as long as the sales tax rate remains the same.
For example, if the original price of an item is x, and the sales tax rate is 8%, then the price after sales tax is x * 1.08. The ratio of the original price to the price after sales tax is x / (x * 1.08) = 1 / 1.08 = 0.93, which is a constant value. This means that the original price and the price after sales tax are in a proportional relationship.
