An ongoing promotion at a department store gives customers 20% off the portion of their bill that is over $100. Ruby's total bill at the department store after the promotion has been applied is $250. If x represents the amount of money Ruby would have spent on the same purchase at the department store without the promotion, which of the following equations best models the situation? A 0.2x + 100 = 250 .. 0.8x +100 = 250 ... 100 +0.2(x- 100) =250 ... 100 +0.8(z - 100) = 250 I would be guessing.
