The rent-a-stall horse barn has stalls for 1000 horses. Forty percent of the stalls are for ponies. On Tuesday, there were 200 ponies and a bunch of quarter horses at the horse barn. The horse barn was 75 percent full.

Total horses = 0.75 * 1000 = 750.

Quarter horses = 750 - 200 ponies =550.

To find the number of quarter horses in the stalls, we first need to calculate the total number of stalls available for ponies.

If 40% of the stalls are for ponies, then the number of stalls for ponies can be found by multiplying 40% (or 0.40) by the total number of stalls:

Number of stalls for ponies = 0.40 x 1000 = 400 stalls.

On Tuesday, there were 200 ponies in the stalls.

So, the remaining number of stalls that were occupied by quarter horses can be found by subtracting the number of pony stalls from the total number of stalls:

Number of stalls occupied by quarter horses = Total number of stalls - Number of stalls for ponies
= 1000 - 400
= 600 stalls.

Since the horse barn was 75% full, we can calculate the number of stalls occupied by quarter horses as a percentage of the total number of stalls:

Number of stalls occupied by quarter horses = 75% x Total number of stalls
= 0.75 x 1000
= 750 stalls.

Now, we can find the number of quarter horses by subtracting the number of pony stalls from the number of stalls occupied by quarter horses:

Number of quarter horses = Number of stalls occupied by quarter horses - Number of stalls for ponies
= 750 - 400
= 350 quarter horses.

Therefore, there were 350 quarter horses in the stalls on Tuesday.

To find out how many quarter horses were in the stalls, we need to first determine the total number of horses in the barn on Tuesday.

We are given that the horse barn has stalls for 1000 horses, and 40% of these stalls are for ponies, which means that 60% of the stalls are for quarter horses.

To find out the number of quarter horse stalls, we can multiply the total number of stalls by 60% (0.60):
Quarter horse stalls = 1000 x 0.60 = 600 stalls

Since the horse barn was 75% full on Tuesday, we can multiply the number of stalls by 75% (0.75) to find out how many horses were in the barn:
Total horses in the barn = 1000 x 0.75 = 750 horses

Now we need to subtract the number of ponies from the total number of horses to find out how many quarter horses were in the stalls:
Number of quarter horses = Total horses - Number of ponies
Number of quarter horses = 750 - 200 = 550 quarter horses

Therefore, there were 550 quarter horses in the stalls on Tuesday.
