At a football game, student tickets cost $3 each, adult tickets are $4.50 each, and children's tickets cost $2.50 each. The number of adult tickets sold was 3 times the number of children’s tickets. The total number of children’s and adult tickets was half the number of student tickets. If the total ticket sales were $9,200, how many of each type of ticket were sold?

x= -3 and

step-by-step explanation:

to find the roots of a cubic, use division or factoring to find the factors then set equal to 0. as this is a difference of cubes, it factors into

where a is the cube root of .

here   this is 27 and the cube root of 27 is 3. so we write using the form:

.

set each factor to 0 and solve for x.

x-3=0

x=3

the quadratic expression does not factor and must be solved using the quadratic formula.

where a = 1, b=3, and c=9

this cubic has two complex roots.

the volume is the product of the area of the base, 3x(3x+4), and the height, 3x-1
