The car show sold the same number of general admission tickets as student discount tickets. The student tickets cost $6.00 less than the general
admission tickets. The total amount of money collected for student tickets was $1800 and for general admission tickets, $3000. What was the price
of a general admission ticket?

$15.00

Step-by-step explanation:

3000-1800

1200

1200/6 (6=difference of general and student)

200

3000/200

15

Double Check

1800/200

9

15(price of general)-9(price of student)

6

since your problem is x^4 = 81, what you have to undeo is the "to the fourth power" part.

the inverse (opposite operation) of "to the fourth power" is "to the fourth root".

  (x^4) ^ ¼   = 81 ^ ¼  

  81 = 3^4     so (3 ^ 4) ^ ¼   =   3 ^ 1   = 3

by hand: (3 ^ 4) ^ ¼   =   3 ^ (4 x ¼) = 3 ^ 1   = 3   (when you take a power to a power, multiply the exponents.)

or, do it by calculator. one way of finding the fourth root is to use ^ (1/4)
