Answer:
6240 + 5t <= 8000
8000 - 6240 >= 5t
Explanation:
weight of horses + weight of tack <= allowable weight of the trailer
weight of horses + weight of tack <= 8000
weight of horses = 6240 lb
6240 + weight of tack <= 8000
The weight of the tack is an average of t per horse, so for the tack for the 5 horses, it weight 5t.
6240 + weight of tack <= 8000
weight of tack = 5t
6240 + 5t <= 8000
One answer is: 6240 + 5t <= 8000
Subtract 6240 from both sides.
5t <= 8000 - 6240
Switch sides (remember to flip the inequality sign.)
8000 - 6240 >= 5t
Another answer is: 8000 - 6240 >= 5t
