Hello, I'm unsure of how to solve this problem. All parts to the question are included.

2.-Luca's inverse demand for public transportation is given by PL(q) = 10 - Zq, where q represents the number of trips per week. Julia's inverse demand is given by P}(q) = 5 - q. The price of a one-way ticket is $2. a) How many trips do Julia and Luca make? How much consumer surplus do they obtain from public transportation? b) The city decided to offer the public transportation service free of charge. To finance the cost of public transportation, the city will raise the taxes by $7 per person. (If you do the math, that seems to be OK.) Obtain the new pattern of public transportation usage by Luca and Julia. How do you think these two consumers feel about the new financing of public transportation
