A The sales tax rate on the item
B The item’s price
C The amount of sales tax on the item
D The item’s size
C, because the tax rate is fixed, the price is the independent quantity since it is deciding how much sales tax on the item, so the amount of sales tax on the item is the dependent quantity because it changes according to the price of the item
