# Math Help - Demand Question

1. ## Demand Question

It has been discovered in a certain state that the relationship between the number of toasters demanded varies linearly with its price. When the price per item was $48 ,2500 items were demanded; When the price was$ 51 , 2465 items were demanded.

Determine the price per item when 2477 toasters are demanded. $_____ Above what price will the demand be zero ?$_____

2. ## Re: Demand Question

unit demand can be expressed as a function of unit cost.

y=f(x)

think of the $and the number of units as x and y coordinates. say that y is the price and x is the demand y1=$48 x1=2500

y2=\$51 x2=2465

so find a linear y=f(x) equation that intercepts those two points and you will arrive at formula that will give you both answers.
