A company has found that the demand for its product varies inversely as the price of the product. when the price xx is 44 dollars, the demand yy is 550550 units. find a mathematical model that gives the demand yy in terms of the price xx in dollars. your answer is y=y= approximate the demand when the price is 8.258.25 dollars. your answer is:

Respuesta :

I am assuming that x = 4 ; y = 550 units ; and price is 8.25

x is the price
y is the demand

"demand varies inversely as the price" - this means that as the price increases, the demand decreases and vice versa.

y = k/x

520 = k / 4
520 * 4 = k
2080 = k 

If k = 2080 ; x = 8.25 ; y = ?

y = k / x
y = 2080 / 8.25
y = 252.12

With a price of 8.25, the demand would approximately be 252.
