# Mixture of nuts

The mixture of nuts should be prepared from almonds, peanuts and cashew nuts ratio 1: 2: 3 (respectively). The price of almonds is 150 CZK/kg, the price of peanuts is 140 CZK/kg and the price of cashew nuts is 180 CZK/kg. The price of the mixture is determined by the ratio in which the nuts are mixed.

What will be the price of one kilogram of the walnut mixture?

Result

c =  161.667 Kc/kg

#### Solution:

$c = \dfrac{ 1 \cdot \ 150 + 2 \cdot \ 140 + 3 \cdot \ 180 }{ 1+2+3 } = \dfrac{ 485 }{ 3 } \doteq 161.6667 = 161.667 \ \text { Kc/kg }$ Our examples were largely sent or created by pupils and students themselves.
