Hi! Let's look at this question. First of all, let's put the question into more understandable terms.
A = 480 + (480 * 1.5)
B = A - (A * 1.5)
The question wants to know, is B = 480.
Break it down.
50% of 480 is 240, so A = 480 + 240 = 720.
A = 720
50% of 720 is 360, so B = 720 - 360 = 360.
B = 360
B =/= 480, so the final price of the car stereo will not be $480.
