Question 1161223
.
<pre>

To solve the problem, I used Excel in my computer.


The printout is this Table below


1975	2000.00
1976	2200.00
1977	2420.00
1978	2662.00
1979	2928.20
1980	3221.02
1981	3543.12
1982	3897.43
1983	4287.18
1984	4715.90

	
the sum	31874.85


The right column is the geometric progression.


Its sum can be calculated using the formula for the sum of an geometric progression,
but again, to facilitate calculations and save my time and efforts, I used Excel spreadsheet.

Solved.
