Problema Solution

past events have shown that if tickets are sold for $20 then 650 people will attend the event. For each raise of $2 in the ticket price, It is estimated that 20 less people will attend the event.

Let x= the price of an individule ticket

and let N(x)= the estimated number of patrons that will attend the event at this ticket price.

The function is N(x).

The slope of N(x) is -20/2 = -10

So we assume N(x) = -10x +b

When x = 20, N(20) = -10*20 +b = -200 +b = 650, b = 850

So N(x) = -10x + 850

So the function N(x) = -10x +850
