The solution set for the inequality x + 4 (x - 3) includes -11 as an element. true false?

The answer is actually True.

Blake's account started with y = 350*x + 480 which at x = 0 (before the first deposit) is y = 350*0 + 480 = 0 + 480 = $480. 

The equation of the line determine by the points given for Eddie's account is this:

y = 475*x + 425.  At x = 0, y = 475*0 + 425 = $425.

Blake: $480 and Eddie: $425
