Please advise, need your help, thanks!

Assume that Jun, Lyle, and Camila are the only buyers of balloons. Their inverse demand functions are: Jun: p = 20 - QJ Lyle: p = 10 QL 2 Camila: p = 5 - 2c 4 where Q J, Q L, and Q c are the quantities demanded by Jun, Lyle, and Camila, respectively, and p is the price of balloons. Suppose the seller of balloons does not have any costs, so the seller only cares about maximizing revenue. Because Jun, Lyle, and Camila always shop together, the seller has to charge them all the same price for balloons. What is the price that maximizes revenue? Round your answer to two decimals. Hint: Notice that while the names may be different, the demand functions of the three buyers are the same as in the previous problem, so you may have already done a lot of the math
