Linear Functions - Applications
Application of problem involving linear functions.
Example:
A cereal company finds that if it spends $40,000 on advertising, then 100,000 boxes of cereal will be sold, and of it spends $60,000, then 200,000 boxes will be sold.
(a) Write a linear equation that relates the amount A spent on ads to the number x of boxes sold.
(b) How much advertising is needed to sell 300,000 boxes of cereal?
(c) Interpret the slope of your linear function.
