Number of horses        1          2          3       4        5       6

Calories needed      15,000     30,000     45,000   60,000   75,000  90,000



Let amount of daily calories needed be C

Since each horse requires 15,000 calories, then expression is:highlight_green%28C+=+15000h%29



Number of calories needed for 6 horses: C = 15,000(6), or 90,000

At $0.15 per 1,000 calories, and with D being the daily cost of feed for 6 horses, we get:

0.15%2FD+=+1000%2F90000______0.15%2FD+=+1%2F90

D = 90(0.15) ------- Cross-multiplying

D, or daily cost for 6 horses = $highlight_green%2813.50%29

You can do the check!!
