Suppose you have coupon dor a 20% discount. you buy a game that costs $38. the sales tax is 5.5%. sales tax applies to thr cost after the discount. what is the total cost of the game?

$32.07

Step-by-step explanation:

Since sales tax is applied to the cost after the discount, you need to first find the cost of the game with a 20% discount.  The original price of the game is $38.  Since the discount is 20%, you are paying 80% of the original price or $38 x 0.80 = $30.40.  With the updated price of the game, you need to add on the cost of sales tax at a rate of 5.5%.  Since you will be paying the cost of the game plus and additional 5.5% sales tax, you can multiply the updated price by 1.055 or:  $30.40 x 1.055 = $32.07.

it is a. 4.2 because 7.6-3.4 gets the remaining length of 4.2. i might be wrong but i am pretty sure this is the answer.
