Lena sells custom-printed t-shirts at her shop. She can sell 120 t-shirts in a month if she charges $14 for each t-shirt. She plans to change the price per t-shirt by a fixed amount n times. The revenue, in dollars, after n changes in price can be modeled by the expression (120 + 5n)(14 - 3n).
Based on the information, complete the sentence about Lena’s t-shirt sales.
For each_______________ in the price per t-shirt by $_____________, Lena will sell _____________t-shirts in a month.
Answer: For each decrease in the price per t-shirt by $3, Lena will sell 5 t-shirts in a month.
The first factor (120 + 5n) represents the number of shirts sold.
The second factor (14 - 3n) represents the price for the t-shirt after the same n changes have been applied.
