basically just count with your hands if you want, start with one finger and say 13 and go up from there, 7th finger is the 19th. Thats my easiest way of doing it. Or you can subtract 24-19 and subtract 12 from the remaining sum

Answer:

z (min) = 705

x₁ = 10

x₂ = 9

Step-by-step explanation:

Let´s call x₁ quantity of food I ( in ou ) and x₂ quantity of food II ( in ou)

units of vit. C units of vit.E Cholesterol by ou

x₁ 32 9 48

x₂ 16 18 25

Objective function z

z = 48*x₁ + 25*x₂ To minimize

Subject to:

1.-Total units of vit. C at least 464

32*x₁ + 16*x₂ ≥ 464

2.- Total units of vit. E at least 252

9*x₁ + 18*x₂ ≥ 252

3.- Quantity of ou per day

x₁ + x₂ ≤ 35

General constraints x₁ ≥ 0 x₂ ≥ 0

Using the on-line simplex method solver (AtoZmaths) and after three iterations the solution is:

z (min) = 705

x₁ = 10

x₂ = 9
