Farmer Jim uses 240 pounds of food each day and he feeds 2160 pounds of food for 9 days given that he keeps 12 horses in the barn and feeds each horse 20 pounds of food a day. This can be obtained by multiplying the number of horses with the pounds per day and then with 9.
Here in the question it is given that,
We have to find the number of pounds of food he use each day and the number of pounds of food he use for 9 days.
Total number of horses in the barn = 12
Pounds of food for one horse in one day = 20 pounds per day
Pounds of food for 12 horses in one day = 20 × 12 = 240 pounds per day
Number of pounds of food he use for 9 days = 240 × 9 = 2160 pounds
Hence Farmer Jim uses 240 pounds of food each day and he feeds 2160 pounds of food for 9 days given that he keeps 12 horses in the barn and feeds each horse 20 pounds of food a day.
