Question

Carl owns a horse trailer that can transport up to 8000 pounds of livestock and tack.

Answer 1

1st One

Reason: The total weight of the horses is 6240 and the weight of the tack is unknown. We know the max weight is 8000 so we know the total weight must be less then 8000

We know that the horses and tack must be equal or less than 8000

6240+t <(equal or less than) 8000
