In a sale, all the prices are reduced by 25%. In the second week of the sale, the prices are reduced by 25% of the previous week’s price. In the third week of the sale, the prices are again reduced by 25% of the previous week’s price. In the fourth week of the sale, the prices are again reduced by 25% of the previous week’s price. Vanellope thinks this will mean that the prices will be reduced to ₱0 after the four reductions because 4 x 25% = 100%. Explain why Vanellope is wrong.

Vanellope is wrong because the price of the items in four weeks after the discounts have been applied should be represented as an exponetial function.

What is the price of the items after four weeks?

The equation that can be used to represent the price of the items after 4 weeks is:

FV = P (1 - r)^n

  • FV = Future value
  • P = Present value
  • R = discount rate
  • N = number of weeks

Assume that the price of an item before the sale began is 100, the price of the item in 4 weeks is: 100( 1 - 0.25)^4 = 31.64
