Answer 1

A monopolist sells 6 units of a product per day at a unit price of $15. if it lowers price to $14, its total revenue increases by $22. this implies that its sales quantity increases by: 8 units. 

To solve for the original sales amount: (6 units)($15) = $90
Next find the new unit amount: (8 units)($14) = $112

The difference between these two is a $22 sales increase which means to have the difference in sales be $22 there were 8 units sold instead of 6 units.
