Answer:
ST, WX
Step-by-step explanation:
If they manage to sell 
tickets, they will earn 
dollars. We want this number to be at least 1000, so the inequality would be
In order to solve this for t, you only need to divide both sides by 15:
So, they need to sell at least 67 tickets to have an income of
dollars
(x+4)^2
Expanded it is (x+4)(x+4)
To solve you need to distribute.
So x^2 +4x +4x +16
Then combine like terms..
x^2 +8x +16
33/20 is the correct answer.
$12 each. $75 - $39 = $36. $36 divided by 3 = $12. Assuming he used all his money.
