Question 245762: a company makes two types of cat food. the first costs $0.35 per can, provides 15 units of vitamin A, and contains 80 calories. The second type costs $0.28 per can, provides 30 units of Vitamin A, and contains 60 calories. The vet recommends that Max get at least 900 units of vitamin A per month and at least 2400 calories. Determine how many cans of each type of cat food should be purchased to minimize the cost if Max's owner can store no more than 50 cans of food. What is the minimum cost?

You can put this solution on YOUR website! Here, sorry I didn't explain it last night, i was tired and it was my last question so I just did it in my head.
b + a > 50
15a + 30b > 900 (vitamans)
80a + 60b > 2400 (calories)
-30a - 60b < -1800
50a > 600
a < or = 12
180 + 30b > 900
30b > 720
b > or = 24
You could graph that, but I just used trial and error and found that 10 and 25 was the best combination.
25 B
10 A
