Answer:
$34.56
Explanation:
We know the initial price is $40.00. We know that the sweatshirt is on sale for 20% off.
We could multiply the initial amount by 0.80 because 1-0.2=0.8.
40*0.8 = 32. Which means that with the discount the sweatshirt cost $32.
Now we need to add tax so the sales tax is 0.08 which we could multiply the discounted amount by 1.08 because 1+0.08=1.08.
32*1.08=34.56. Which means your finally selling price of the sweatshirt is $34.56.
