To find:The correct choice for an equation representing amount of sales tax and price of the item proportional relationship.

Answer to Problem 21STP
The correct choice is (D) that represents an equation foramount of sales tax and price of the item proportional relationship.
Explanation of Solution
Given information: The sales tax rateis
Calculation:
The conversion of sales tax rate from percentage to decimal is:
The equationfor proportional relationships is:
Here,
The amount of sales tax paid to the price of the item purchased, in which the price of the item is
Substitute
Therefore, the correct choice is (D) that represents an equation for amount of sales tax and price of the item proportional relationship.
