The Wares want to buy a new computer. The regular price is $1,049. The store is offering a 20% discount and a sales tax of 4.25% is added after the discount. What is the total cost?

Answer: The total cost is $874.86

Steps:

Start with determining the discounted price:

$1049 - discount 20% = 1049 - (0.2 * 1049) = 0.8*1049 = $839.2

At the checkout they will add the sales tax on this (discounted) price, the tax amount is worth 4.25%

tax = 839 * 0.0425 = $35.66

and that gets added to the total to pay:

$839.20 + $35.66 = $874.86

so if you offer 20% off of 1,049 you get 209.8. If the tax is 4.25% then do the math -._-. (thinking) ... 200.8835 and just do the lil bit of math to find your answer.
