At present, the firm is the only water park in the lake region, but the Aquatic Ltd management has learnt that another facility is being planned by Mt Kenya Mafia for nearby community. After the competing park opens, management expects to get 100,000 patrons to Aquatic fish Limited each year, prices would have to be reduced and the average revenue would drop to Ksh 90.
The management of Aquatic believes it immediately reduces prices and keeps them at a low level for two years, it can prevent the Mafias from opening. The necessary price cut would reduce average revenue to Kshs 600 but would increase attendance to 12,000
