Increase. Total revenue is simply asking how much money total comes in from sales. It does not take into account expenses, costs, etc.. In this case, all you have to do is figure out how much money they make at each price amount. At $10, they make $30,000 ($10 x 3,000). When the price is reduced to $8, they make $40,000 ($8 x 5,000). Obviously, total revenue has increased.
