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

where is the diagram? shown below where? ?

step-by-step explanation:

the functions have the same rate of change i think. i narrowed it down to this answer and "the rate of change of tour 1 is greater" but i got it wrong using that answer so im assuming its the answer above. (this is a question i also answered from the iready site if anyone needs a reference)
