Answer:
Step-by-step explanation:
The inverse proportional formula is
[tex]y=\frac{k}{x}[/tex] where y is the number of cookies sold, and x is the price per cookie. If we fill in the info given, we can find what it is we are being asked.
When x = 4 (the price of each cookie is $4), 50 cookies are sold (y = 50). Filling in to solve for k:
[tex]50=\frac{k}{4}[/tex] so
k = 200. Using that value of k along with a price of 2 (x = 2), we can find the number of cookies sold, y.
[tex]y=\frac{200}{2}[/tex] so
y = 100 cookies sold when the price is $2 per cookie.
