100 tickets were sold.
The total amount of the tickets sold is = 5 * 100 = $500. 
First prize given = $100
Second prize worth = $20 * 5 = $100
Total worth of prize + $100 + $100 = $200.
Net amount of tickets sold = $500 - $200 = $300
Expected price of each ticket sold = $300/100 = 3.
Therefore, the real price of each ticket sold is $3.

Select the correct answer. Simplify the expression below. 4x(3x − 7) − 19x2 A. -7x2 − 7 B. -35x2 C. -7x2 − 28x D. -31x2 − 28x
morpeh [17]

Answer:

C. -7x^2-28x

Step-by-step explanation:

The given expression is 4x(3x-7)-19x^2

We apply the distributive property to expand the parenthesis

12x^2-28x-19x^2

Regroup similar terms to get:

12x^2-19x^2-28x

Combine the similar terms to obtain:

-7x^2-28x

The correct option is C.
