Option D
Function used to determine the profit the theater group earns from selling "x" tickets is f(x) = 12.50x - 150
<h3><u>Solution:</u></h3>Given that a theater group charges $12.50 per ticket for its opening play of the season
Also given that Production costs for the play are $150
To find: function used to determine the profit the theater group earns from selling "x" tickets
So "x" represents the number of tickets sold
Cost per ticket = $ 12.50
Production costs = 150
Then the profit the theater group earns from selling "x" tickets is:
<em>Profit earned from selling "x" tickets = cost of "x" tickets - production cost</em>
Let f(x) denotes profit earned from selling "x" tickets
f(x) = 12.50x - 150
Thus option D is correct
