now, if the early ones cost each one 6 bucks, then the cost for all of them is 6*x, or 6x.
the ones sold at the door are 10 bucks each, and therefore their total cost is 10(x + 206).
now, we know sales in total for both was 6828, therefore,
and surely you'd know what that is.
how many were sold at the door? well, x + 206.
