MOVIE TICKETS. For a class trip, a teacher bought 25 student tickets (s) and 5 adult tickets (a). Write an algebraic expression for the total cost of the tickets purchased.
If student tickets cost $4 each and adult tickets cost $6 each, how much money did the teacher spend on tickets?

the number of the people going.

step-by-step explanation:

the cost to buy one movie ticket is $7. if the total cost for the movie is a function of how many people go, then the input is : the number of the people going.

constant of proportionality = 3 and the equation is c = 3p.

step-by-step explanation:

c = kp   where c = amount of caffeine in mg., p = oz of pepsi and k is the constant of proportionality.

substituting the values given:

24 = 8k

k = 3.

the same value of k will be obtained if we substitute the other given values.
