Question

You sell hockey goals for $200 each. weekly sales are 60 units. you estimate that for every $10 you increase the price, sales drop by 3 units per week. what will be your weekly revenue from hockey goals at a price of $300?

Answer 1

If for every $10 increase sales drop by 3 units when you increase to $300 you will lose 30 units. 

($10)(10) = 100
(10)(3) = 30

60 units - 30 units = 30 units. 
($300)(30) = $9,000 is your weekly revenue at a price of $300 per unit.
