x = Nougat in 100g
y = Krokant in 100g
I. x + y = 50 | x = 50 - y
II. x * 4,99 + y * 3,19 = 50 * 3,99
I in II
(50 - y) * 4,99 + y * 3,19 = 50 * 3,99
249,5 - 4,99y + 3,19y = 50 * 3,99
249,5 - 50 * 3,99 = 4,99y - 3,19y
50 = 1,8y
y = 250/9
x = 200/9
Nougat: 200/9g * 100 ≈ 2,22kg
Krokant: 250/9g * 100 ≈ 2,78g
