An Engineer is faced with a prospect of a fluctuating future budget for the maintenance of a particular machine. During each of the first five years PHP 100,000 per year will be budgeted. During the second five years the annual budget will be PHP 150,000. In addition, PHP 350,000 will be budgeted for an overhaul of the machine at the end of the fourth year, and another P350,000 for an overhaul at the end of the eight year.

The Engineer wonders what uniform annual expenditure would be equivalent to these fluctuating amounts, assuming compound interest at 6% per annum. Compute the equivalent uniform annual expenditures for the 10 year period.
