There is no clearly defined question and grammatical errors are in the text above. That said, the text begs the question why does Edmund consume cassettes? The answer is that the cassettes attract billy goats and the goats eat the garbage. Edmund can earn a living as long as each $6 cassette attracts enough of the goats to consume 3 garbage sacks. To be profitable, one cassette must attract enough goats to consume 4 sacks of garbage.
