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 5.25% is added after the discount. what is the total cost? plz put the way how to do it

Multiply the regular price ($1,049) by the Percent Discount (20%). To do this, multiply 1,049 by 0.2 :
1,049(0.2)=$209.8

After multiplying, you get the amount taken off by the discount. So you subtract the amount you got ($209.8) from the original amount ($1049) :
$1049-$209.8=$839.2

Now that you've calculated the discount price, you can calculate the sales tax. Make sure you do this part second, because it says to do so in the problem.

To calculate the sales tax, you do the same as above. Multiply your NEW cost ($839.2) by the sales tax (5.25%). The equation is:
$839.2(5.25%)=$44.058

Round $44.058 to $44.06. Since this is a Sales Tax, you add this on to your previous amount of $839.2
$839.2+$44.06=$883.26

The final cost of the computer is $883.26

1+1=22×1=22-1=11-1=1duh
