Question

Assume rocky mountain railway is considering hiring a reservations agency to handle passenger reservations. The agency would charge a flat fee of $12000 per month, plus $1 per passenger reservation. What is the the total reservation cost if 50,000 passengers take the trip next month?

Answer 1

Alright, so we start out with $12000, and we'd add from there. Since we add 1$ for every passenger, our equation with p being the number of passengers would be 1*p (e.g. for 1 passenger we have 1*1=1, 2 passengers we have 1+1(2 times)=2). Substituting 50,000 for p, we have 1*50,000=50,000. Next, we have to add 12,000 to that (as that's a flat fee) to get 50000+12000=62000
