a. If a company increases advertising from $10M to $15M per year, by what percent would you forecast sales to increase? Please clearly show your calculation and logic. Assume that the product is a sports drink like Powerade.
AED= .025 prior
Increase=15-10/10=50
.025*50=12.5
b. If a company has current sales of $100M, what is the ROI for the prior question?
