More revenue would be generated at $5 than $17 because on the graph, when the price is at $5, there is about $3750 in revenue compared to when the price is $17, the revenue is $2500.
The company should sell their product at $10. At this price, the revenue they will make is $5,000.
The domain is the possible intervals in which x lies. Therefore, the domain is : 0 ≤ p ≤ 20.
If 50 is your 100%, take 100 and 90 for example it would be obvious that is it 10% off, so with 50 since it is half of 100 you double the 10% which will be 20%. :)
