You will save 5.00 units of currency.
12 x 100/60: 20%
0.1 x $50.00 = $5.00
$450.00 X 10% = 4.50, the dress will cost $445.50
Assuming that there is no sales tax, you will multiply 50.00 by 0.10 (that is how you calculate percents) to get 5.00. You subtract this from the original price, to get 45.00. Again, this is assuming no sales tax. :)
