Step-by-step explanation:

(a). How many more people said their favorite vehicle color was blue compared to those who said white explain?

250 people

32% said blue. 32% of 250 is 0.32*250 = 80

24% said white. 24% of 250 is 0.24*250 = 60

graphically?   well, you graph them both, the solutions is where they both intersect each other, since there are two solutions, meaning they will meet twice, or namely the linear will run into the quadratic curve twice, and where they meet, those x,y coordinates are the solutions to the system.
