 d. x + 0.1y = 75

$$y = 75 +.10x$$
The delivery person will earn $75 regardless of if he delivers any papers (x=0). However, each time he delivers a newspaper, he earns $0.10 per paper. Therefore, $0.10 is tied to the variable, as he can deliver an unknown amount of papers.

As both numbers are positive, we can shuffle them around without having to worry about addition or subtraction signs. So:

$$y = 75 + .10x$$ or $$y = .10x+75$$
