If the total cost for the clothes is $78, then one pair of socks cost $3.00. ...4 shirts @15.00 each = 60.00. [ $78.00-60.00 = 18.00 18/6=$3.00 ]
So A.

Well...we know the total cost is 78

And we know he spent (15 * 4) = 60 dollars on shirts...

so now he has 78 - 60 = 18 dollars to work with...

He wants to buy 6 socks...at the same price...to make that 18 dollars...so

6x = 18

divide both sides by 6 and solve for 'x'
