Question

please help!

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

Answer 1

2$ per litre

Answer 2

So we've got (7*4)+(14*1) to give use the total cost of the mixture, which is 42. Dividing that by the total of 21kg (7 of soybean + 14 of canola oil) gives us $2/kg.

Answer 3

thank you!
