Question

Sales tax is currently 9.4 %. Write an algebraic expression to represent the total amount paid for an item that costs D dollars after tax is added to the purchase.

Answer 1

D = p +(.094×p)

Explanation:

1. Take 9.4% and make it a decimal. 9.4%=0.094

2. Multiply 0.094 by the original price of the item (seen above as the variable p).

3. Next find the sum of the original price and the number from step 2.

Plugging in some example numbers, we can see this in the expression. Let's leave D as an unknown but make the original price $24. The product of 24 and 0.094 is 2.256. We add this new number to 24 and get 26.256. That's our answer! If the sales tax on a $24 item is 9.4%, the item costs $26.256 after tax is added to the purchase.
