Hello there! So the snow blowers were bought $90 each. 200 of them were bought that that price. Let’s multiply. 200 * 90 is 18,000. $18,000 of snow blowers were bought. All 200 of them were marked up to $120 for each snow blower. 200 * 120 = 24,000. That’s $24,000 worth sold. But we need to know the profit, because they don’t actually earn all of it. We will find the profit by subtracting both numbers. 24,000 - 18,000 is 6,000. There. $6,000 were made in profit.
