1. The problem statement, all variables and given/known data A street vendor sells a hamburgers, b hot dogs, and c soft drinks on a given day. He charges $2 for a hamburger, $1.50 for a hot dog, and $1 for a soft drink. If A = <a, b, c>, and P = <2, 1.5, 1> , what is the meaning of the dot product A * P 2. Relevant equations - Dot product of <x, y, z> and <a, b, c> is xa + yb + zc - Two vectors multiply to become a scalar. 3. The attempt at a solution I have no clue what the significance of the dot product in this situation is. Additionally, I don't see how $1.50 and nor the number of hot dogs are vectors.
