Assume that my lawn is encroaching my garden and reduces my space, on average, by 8% each year.
If the garden started out at 575 square feet, approximately how many square feet will there be in 11 years?
after 1 year you'll have 100-8=92% of your space left. after 2 yrs, 92% of that, etc. after k years you have
area(k) = 575 (0.92)k sq ft.
area(11) = 575 (0.92)11 = 229.7915 sq ft.
