Large boxes weigh 75 pounds, and small boxes weigh 40 pounds.

a. write an inequality that represents the numbers of large, x, and small, y, boxes a 200-pound delivery person can take on the elevator.

b. select the reason(s) why some solutions of the inequality might not be practical in real life.

> the number of boxes must be a whole number.

> the number of boxes must be a rational number.

> it is unlikely that one person will carry 20 large boxes.

> it is unlikely that one person will carry 45 small boxes.

for a, i got 75x + 40y ≤ 200 i got it wrong but i'm not sure why?
