Advertisers want to create "awareness," which is whether a consumer even knows about a business. If your business starts with 3% awareness and grows awareness by 5% per week (compounded), how long will it take to reach 75% awareness? The formula for compound growth is E = B x (1 + R)T, where E is ending value, B is beginning value, R is rate of growth, and T is the amount of time. Can someone give a detailed explanation step by step as well? Thank you!
