Cari owns a horse farm and a horse trailer that can transport up to 8,000 pounds of livestock and tack. she travels with 5 horses whose combined weight is 6,240 pounds. let t represent the average weight of tack per horse. which of the following inequalities could be used to determine the weight of tack cari can allow for each horse?

If the maximum capacity of the trailer is 8,000 pounds, and the combined weight of the horses Cari is carrying is 6,240 pounds, the weight left in the truck for tack is 1,760. This was found by solving 8,000 - 6,240.
You then divide this difference by 5, the amount of weight per horse evenly divided so it is the average weight: 1,760 / 5 = 352.
Since the trailer can carry "up to" 8,000 pounds, the combined weight of tack the horses carry can be "up to" 1,760 pounds, and the weight of tack each horse carries can be "up to" 352 pounds. "Up to" is represented by the "less than OR equal to" symbol.
