The equation for the motion of an object with constant acceleration is d=vt+0.5at? where d is distance traveled in ft, v is starting velocity in ft/s, a is acceleration in
ft/s2, and t is time in seconds. A racecar begins with a velocity of 200 ft/s and
accelerates at 100 ft/s2.

Which situation can be modeled by the inequality 5 + 10w ≥ 45? a. you start with $5 and save $10 a week until you have at least $45. b. you start with 5 baseball cards and purchase 10 cards every week until you have at most 45 cards. c. you start with 5 water bottles and purchases cases of 10 water bottles each until you have a total of 45 water bottles. d. you spend $5 plus $10 per week until you have less than $45.

Me. i can't figure out this question. give an explanation too. .
