i need help starting this problem i don't know where to begin

A WCU Entrepreneurship major is starting a house painting business. Based on responses to local advertising and to informal surveys, she anticipates getting four painting jobs per week (Poisson distributed). She has estimated it will take a 4-person team 0.7 weeks to compete a typical job (exponentially distributed).

Determine the number of teams needed if the goal is to have customers wait no more than 2 weeks to have their house painted.

If the average price for a painting job is $6,800 and the painters each make $500/week, will she make any money? If so, how much? Show how you arrived at the answer.
