Laboratory mice are fed with a mixture of two foods that contain two essential nutrients. Food 1 contains 3 units of nutrient A and 2 units of nutrient B per ounce; food 2 contains 4 units of nutrient A and 5 units of nutrient B per ounce. In what proportion should you mix the food if the mice require the nutrients A and B in equal amounts? Assume now that the mice require the nutrients A and B in the ratio1 : 2. Is it possible to satisfy their dietary needs with the two foods available? any help would be greatly appreciated!! Thanks.

So our food $F=pf_1 + f_2 = p(3A + 2B) + (4A + 5B)$. We require equal amounts of A and B. So$$3p + 4 = 2p + 5$$where the left hand side is the amount of A and the right hand side is the amount of B.
