It cannot be equivalent unless you can divide 5/6 into 4/5 and multiply 4/5 into 5/6, but you can't. You can only add both by one which doesn't make it equivalent in any way
we know that the colony is doubling, namely the rate of growth is 100% of whatever is existent, thus

3,500 (.024) = 84
84 (5) = $420 in simple interest
