Weegy: (100 – 12) – 3x would be the correct answer because:
100 is the total amount he paid
12 is the cost of pants
because we don't know the price of shirts yet so it would be called x
He buy in total of 3 shirts so the equation for the price would be [ 3 * x = 3x
So it would be:
total money paid - pants costs - shirts cost
= 100 - 12 - 3x or (100 - 12) -3x.
