A clothing store discounts items on a regular schedule. Each week, the price of an item is reduced. The prices for one item are in the table below. Week 0 is the starting price of the item. Determine a linear or exponential equation that represents the relationship between the week and the price of the item.
[list=1] [*]Create a graph of the data. [*]Determine if a linear or exponential equation could represent the data. [*]Find the common ratio between the terms. [*]Use the value of the equation at [math]x [/math] = 0 and the common ratio to write an equation to represent the relationship.
