Calculation

At Present After 10 Years After 15 Years After 20 Years
Population (No.) 5000 =5000 * (1+5%)^10 =5000 * (1+5%)^15 =5000 * (1+5%)^20
Percapital Expenditure ($) 300 =300 * (1+7%)^10 =300 * (1+7%)^15 =300 * (1+7%)^20
Population grows at 5% per annum so used 5% for compounding and the respective period is used as exponential
Expenditure grows at 7% per annum so used 7% for compounding and the respective period is used as exponential
After Calculation
At Present After 10 Years After 15 Years After 20 Years
Population (No.) 5000                             8,144                           10,395                           13,266
Percapital Expenditure ($) 300                                590                                 828                              1,161
Total Budget = Population * Percapital Expenditure
At Present After 10 Years After 15 Years After 20 Years
Total Budget =5000*300 =8144*590 =10395*828 =13266*1161
`Total Budget in $    1,500,000                     4,806,423                      8,603,743                    15,401,137
