15 points and brainiest to the right answer : ) what is the rate (in dollars per ticket)? how much money will the theater earn if it sells 150 tickets? that is all i need to know, you so much to whoever me!

What is the rate (in dollars per ticket)?  

(40, 600) and (20, 300)

Rate = (600 - 300)/(40 - 20) = 300/20 = 15

Rate = $15 per ticket

How much money will the theater earn if it sells 150 tickets?

$15 x 150 = 2250

Theater earn will earn $2,250  if it sells 150 tickets

2(2x + 3) = -4 + 2(2x + 5)

4x + 6 = -4 + 4x + 10

4x + 6 = 4x + 6

4x - 6 + 6 = 4x - 6 + 6

4x = 4x

x = x
