Answer:
The correct answer,for each decrease in the price per T-shirt by $3,Lena sells 5 more
Explanation:
First and foremost,total revenue is quantity sold multiplied by price per unit.
In this case, revenue is (120+5n)*(14-3n)
(120+5n) represents the quantity sold
(14-3n) depicts the price per shirt
14-3n,the -3n implies that price was decreased by $3 for n number of times
120+5n,the 5n implies that quantity sold increased by 5 units for n number of times
The rationale is that when price is reduced,quantity sold increases,inverse relationship between price of shirt and quantity of shirts sold
The correct answer,for each decrease in the price per T-shirt by $3,Lena sells 5 more
