Question 181364
Solve Variation Problem 
Sam's found that the demand for coke products
varies inversely as the price of the product. When the price
of a coke product is $2.75, the weekly demand is 1250.
Find the weekly demand if the price is raised to $4.00.

:
demand for coke products be d
price of the product call p
:
dp=k where k is the constant of variation
:
1250(2.75)=3437.5
:
so k = 3437.5
:
d(4)=3437.5
:
${{{highlight(d=859.38)}}}demand at price of $4
:
