Answer:
Explanation:
Given:
Qd = 479 - 3P
where:
Qd = the quantity of residential landscape cleanings per week that people in the local area would be willing to purchase
P = monthly price in dollars
We plug in the given price of 39 dollars per month into Qd = 479 - 3P. So,
[tex]\begin{gathered} Qd=\text{ 479-3p} \\ =479-3(39) \\ \text{Simplify} \\ =479-117 \\ Qd=362 \end{gathered}[/tex]Therefore, the quantity demanded at a price of 39 dollars per month is 362.
