Dennis wants to buy 4 pairs of pants which cost 110x4= $<<110*4=440>>440.
And he also wants to buy 2 pairs of socks that cost 60x2= $<<60*2=120>>120.
The total amount he needs to spend without the discount is 440+120= $<<440+120=560>>560.
The discount he will have amounts to $560x.0.30= $168.00.
So the total amount he needs to spend after deducting the discount from the total amount is 560-168=$<<560-168=392>>392.
