The school that William goes to is selling tickers to see a Star Wars Movie premiere. On the first day of ticket sales the school sold 35 adult tickets and 90 student tickets
for a total of $695. On the second day of sales, they took in $320 by selling 35 adult
tickets and 15 student tickets.
What is the cost of one student ticket? (no need to include a dollar sign or s an a =
with your answer, just the number)

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 answer for this is 0.25 km. : )
