7kg of soybean oil which costs $4/kg were combined with 14kg of canola oil which cost $1/kg. find the cost per kg mixture

Cost per kg = $2

Step-by-step explanation:

Given that:

7kg of soybean oil costs $4/kg

So 7kg of soybean oil will cost = 7 * 4 = $28

14kg of canola oil costs $1/kg

So 14kg of canola oil will cost = 1* 14 = $14

Now for mixture:

Quantity of (soybean oil + canola oil) = Cost of  (soybean oil + canola oil)

7kg + 14kg = $28 + $14

21kg = $42

Now finding cost per kg of mixture:

Cost per kg = $42/21

Cost per kg = $2
