Super easy!

A jet carries 342 passengers with 36 in first-class and the rest in coach. Suppose a first class ticket to fly from Los Angeles to Chicago costs $750 and a coach ticket costs $450. Use the four step problem solving plan to find the greatest possible ticket sales on one flight.

I'm an idiot, could you show me the steps and the solution?

"A man runs at speed v to catch the bus. At t=0, he is still a distance of 10m from the door when the bus starts to accelerate at a constant rate of 0.38 m/s^2. What is the minimum speed the man can run and still board the bus."

I know this involves a quadratic because I assume you have to use the equation [(xf) = (xi) + (vi)(t) + (0.5)(a)(t^2)], and that [b^2 - 4ac] (from under the root in solving a quadratic using the Q.F.) must equal zero in order to ensure that the man's speed is the minimum it can be so that he and the bus are in the same place at the same time... I'm just having difficulty setting up the problem properly.

Thanks in advance!

2+2

I've been trying to figure it out for hours. I went to tutoring and they couldn't help, I tried it in my calculator and it even broke, I called Chuck Norris and he roundhouse kicked me, I tried with my fingers and toes and all the nails broke, I called Jesica Simpson and she told me it was a kind of fish that usually comes in a can, I asked my math teacher and she doesn't get it neither; we are working together to solve it by next week!

What should I do?

Thanks a lot for your help
