Adult and student tickets were sold for a school concert. the adult tickets cost $12 each, and the student tickets cost $8 each. if a total of 360 tickets were sold for $3,480, how many of each kind of ticket were sold?

the number of adult tickets sold is 150

the number of student tickets sold is 210

Step-by-step explanation:

Let x represent the number of adult tickets sold.

Let y represent the number of student tickets sold.

The adult tickets cost $12 each, and the student tickets cost $8 each. The total cost of tickets sold $3,480. This means that

12x + 8y = 3480 - - - - - - - - - -1

The total number of tickets sold is 360. This means that

x + y = 360 - - - - - - - - - -2

Multiplying equation 1 by 1 and equation 2 by 12, it becomes

12x + 8y = 3480

12x + 12y = 4320

Subtracting

-4y = -840

y = -840/-4 = 210

Substituting y = 210 into equation 2, it becomes

x = 360 - y = 360 - 210

x = 150

i found two solutions,   n = 2 • ± √3 = ± 3.4641

step-by-step explanation:

i believe that the slope of the line is -5
