To supplement her income, Ms. McCormick grows lucky bamboo in her backyard garden and
sells ceramic pots of bamboo to customers online. She has found that when she decreases
the price per pot, the number of pots she sells each month increases. Her monthly revenue
can be modeled by the expression p(96 - 4p), where p is the price Ms. McCormick charges
for each pot of bamboo.
What does the quantity 96 - 4p represent in the expression?
