grigory [225]

Answer:

  • 4 2/3 pounds of cereal Y; none of cereal X
  • $37.33 is the minimum cost

Step-by-step explanation:

The quantity of vitamin A in the food is ...

  10X +30Y ≥ 140

and vitamin B ...

  20X +50Y ≥ 140

The cost, which we want to minimize is ...

  12X +8Y

__

A graph shows that any diet meeting the requirement for vitamin A will also meet the requirement for vitamin B. Vitamin A in the form of cereal X costs ...

  $12/(10 mg) = $1.20/mg

In the form of cereal Y, it costs ...

  $8/(30 mg) ≈ $0.27/mg

So, cost is minimized by satisfying the vitamin requirements using cereal Y exclusively. That cost is $37.33 for 4 2/3 pounds of cereal Y only.

v =  \frac{1}{3} ah
Where v is the volume, a is the base area and h is the height.

We can then put the given information into the formula:

176 = (1/3)(3x × x)(11)

(176 × 3) / 11 = 3x^2

3x^2 = 48

x^2 = 48/3

x = _/16

x = 4
