4 because when you add 2 and 2 it equals 4
Alright, we know that we have to spend 499 dollars on a computer as a base cost. Next, we have to buy 49.99 * x dollars worth of games (since games are 49.99 each), adding up to 499+49.99*x
Alright, so plugging 5 in for x, we get 499+49.99*5=744.95
Since one controller is 24.99, the money for buying a y amount of controllers would be 24.99*y., making the expression 499+49.99x+24.99y
Since in part D, there are no games, we plug these in to get
499+49.99*0++24.99*3=573.97 dollars
