(a) As an economic advisor to the government, you analyse possible projects that maximise the utility and welfare of the country. You have been tasked with analysing replacement technology for Australia?s east coast early tsunami warning system. The current system is outdated and lacks the range of detection of newer systems. The current system is also very expensive to maintain and operate. There are currently two designs on the market that offer a suitable replacement solution. To replace the current system it is anticipated that 1000 units of either of the Hello Tsunami (HT) or Big Wave Warning System (BWWS) be used to cover the same detection area as the existing system.Please see the attachement.
