Acompany manufactures and sells video games. a survey of video game stores indicated that at a price of $69 each, the demand would be 200 games, and at a price of $39 each, the demand would be 1,100 games. if a linear relationship between price and demand exists, which of the following equations models the price-demand relationship?

(let x represent the price per video game and y represent the demand.)
(answers are in the snip)

If the equilibrium is such that only 12000 units are sold for $27, then the total earnings from the given scenario is $324,000. The supply equation would then be,

       supply: 324000 = 6p   ; p = 324000/6 = 54000

       demand: 324000 = 69p ; p = 324000/69 = 4695.65 ≈ 4696

answer: the answer is (b) amie should have multiplied

step-by-step explanation: given a sphere and a cylinder with same radius and height.

let, 'r' be the radius of the cylinder and sphere and 'h' be the height of the cylinder. according to the question,

r = h.

now, the volume of the sphere will be

and the volume of the cylinder will be

therefore, we have

thus, ammie should have multiplied the volume of the sphere
