First we need to make a valid equation. Let's assign the constant sale price with a variable
x. We should bring two cases -- case 1st with the 8% and case 2nd with the 5% into equilibrium. So we have x+x(0.08) =x+x(0.05)+12. We need to add 12 to the 2nd case to maintain the equation. After solving the equation, we get that x equals to 400. But be
CAREFUL and do not jump into the answer choices. I will advise everyone to reread the problem after relatively completing it. In the last step, we need to add 32 (which is the 8% of the 400) to 400 to get the satisfying answer.
