Answer:
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
