If f(x) = 3x - 12 and x = 9

then substitute 9 in place of x

f(9) = 3(9) - 12

f(9) = 27 - 12

f(9) = 15

A game of chance is begun. You will pick one number out of 300. If your number is picked you win $30,000. At what point is it no
garik1379 [7]

Answer:

<$100 / greater than $100

Step-by-step explanation:

30,000/300=100

If you spent $100 per spin and won 1 out of 300 games, there would be no net gain.

If you spent anything more than $100, then you would lose more money than you gained if you won 1 out of 300 games.
