if n items are sold for $p each, revenue is $np. If we reduce the price by 30%, the new price is 0.7p. If we increase the number sold by 80%, the new number sold is 1.8n. So the new revenue is (0.7p)(1.8n) = 1.26np, which is 1.26 times the old revenue, so is 26% greater.   26% increaseNSWER:26% increase
