An album is downloaded 10000 times per week when its price is $12. It is downloaded 20000 times per week when the price drops to $9. Find the demand equation, assuming it is linear. The equation should express price p in terms of quantity q. a. P= b. Find the price at which the demand will reach 40000 downloads per week.
Equations and Inequations
Equations and inequalities describe the relationship between two mathematical expressions.
Linear Functions
A linear function can just be a constant, or it can be the constant multiplied with the variable like x or y. If the variables are of the form, x2, x1/2 or y2 it is not linear. The exponent over the variables should always be 1.
