First set up the equation.
x + 3x = 648
Then solve for x.
4x = 648
Divide both sides by 4.
x = 162. So the answer for the system would be $162 and the price for the games would be $486. Add the two up to check your work and you will get $648. Hope this helped!

Answer:
The average number of trials required to get the first success
2.40/6 I believe tell me if it is right
From what I know this graph looks like that of a modulus function except it's shifted 1 unit to right and 1 unit below the origin.
So the original equation must be:
y = |x|
And the transformed equation (aka the equation if this graph) must be,
y+1 = |x| -1
y = |x| -2
