1(1 - 1/4) = 3/4
3/4 * (1 - 1/4) = 9/16
9/16 * (1 - 1/9) = 8/16 = 1/2
so 3400 = 1/2 of the starting amount.
check:
6800 - 1700 = 5100
5100 - 1275 = 3825
3825 - 425 = 3400
3/4 * (1 - 1/4) = 9/16
9/16 * (1 - 1/9) = 8/16 = 1/2
so 3400 = 1/2 of the starting amount.
check:
6800 - 1700 = 5100
5100 - 1275 = 3825
3825 - 425 = 3400
