P(n) models the fundraiser's profit (in dollars) where n represents the number of tickets that are sold. The equation is expressed as
P(n) = 70n - 1500
A negative profit means the expenses exceeded the income from tickets. Looking at the model, for the charity organization to make profits, the product of the number of tickets sold and the cost per ticket must exceed $1500. If it is below $1500, then it is a negative profit. This means that the expenses is $1500
225 (since the fraction is over 180° (because 5Π/4 > Π we know that the answer must be bigger than 180° (because 180° = Π (radians) and its less than 270° because 270° = 3Π/2 or 6π/4
