3. A cereal company finds that the number of people who will buy one of its products
in the first month that the product is introduced is linearly related to the amount of
money it spends on advertising. If it spends $40, 000 on advertising, then 100, 000
boxes of cereal will be sold, and if it spends $60, 000, then 200, 000 boxes will be sold.
a). Write a linear equation that relates the amount A spent on advertising to the
number r of boxes the company aims to sell.
b). How much expenditure on advertising is needed to sell 300,000 boxes of cereal?
c). Interpret the slope.
