Alex is selling tickets to a school play. an adult ticket costs $6.50 and a student ticket costs $4.00. alex sells x adult tickets and 12 student tickets. write a function, f (x), to represent how much money alex collected from selling tickets.

Step-by-step explanation:

Let

x ----> the number of adult tickets

f(x) ----> amount of money collected

To find the amount collected multiply the number of adult tickets by the cost and multiply the number of student tickets  by the cost, and then sum the two quantities

The linear equation that represent this problem is

80x^8−68x^6+16^5−20x^4−4x^3+8x^2

hope i'm right lol
