8kg of coffee costing #1200 a kg is mixed with 12 kg of another kind of coffee costing #1800 a kg what is the cost of the mixture per kg.

Answer 1

First, we need to find the total cost of each type of coffee:

8 kg x #1200/kg = #9600

12 kg x #1800/kg = #21600

Then, we add the two costs together:

#9600 + #21600 = #31200

Next, we find the total weight of the mixture:

8 kg + 12 kg = 20 kg

Finally, we divide the total cost by the total weight to find the cost per kg:

#31200 ÷ 20 kg = #1560/kg

Therefore, the cost of the mixture per kg is #1560.
