Answer:

See below.

Step-by-step explanation:

I'll work it out myself,  then we should be able to see the mistake:-

6 ∛ (64x^5y^9)

= 6 * 4 * x^(5/3) * y^3

= 24 x^(3/3) * x^(2/3) y^3

= 24 x y^3 ∛(x^2)

You've got confused withe the cube root  (∛) on the first line. You've interpreted it   as ' 3  times the square root' so you were on the wrong road from the beginning.

Note that y^9 has cube root y^(9/ 3) = y^3  and x^5 has cube root of x^(5/3).   The square root of x^9 is x^(9/2).

The expression that represents the total amount that can be raised from selling 50 tickets is -2t + 250 and the total amount that can be raised is $194.

What is total revenue?

Total revenue is the amount of money earned by a company from the sale of its goods and services. In other words, businesses use this metric to determine how well their core revenue-generating operations are performing. Total revenue is directly related to marginal revenue.

Number of tickets that will be sold = 50

Number of student tickets that will be sold = t

Number of adult tickets that will be sold = 50 - t

The total amount of money that can be raised from selling 50 tickets is the sum of the total amount raised from selling student tickets and adult tickets.

Total revenue = total amount raised from selling students tickets + total amount raised from selling adults tickets

Total revenue = [3 x t] + [(50 -t) x $5]

Total revenue = $3t + $250 - 5t

Total revenue = -2t + 250

Total revenue = -2(28) + 250

Total revenue = -56 + 250 = $194

Hence, the expression that represents the total amount that can be raised from selling 50 tickets is -2t + 250, and the total amount that can be raised is $194.
