Answer:
y(x)=5x for (20≥x≤40)
Explanation:
Step one :
Given data
Cost of ticket =$5
Given that the number of tickets to be sold for the tour to happen should be at least 20 and not more than 40
Step two :
Let the number of tickets be x
And let the revenue or income be y
The function for the cost is expressed linearly as
y(x)=5x
The domain is y(x)=5x for (20≥x≤40)
