The local church delegates would like to build a community centre for social activities. The plan is to start with building operations in exactly three years' time. The church community deposits an initial R75 000 into a savings account and adds an extra R75 000 exactly two years later. The initial interest rate is set at 12% per annum compounded monthly but is adjusted eighteen months after the initial deposit to 11.4% per annum continuous compounding. Find the value of the investment when the building operations are due to start.
