If 8kg of coffee costing $2000 a kg is mixed with 12kg of another kind of coffee costing $2200. What is the cost of the mixture per kg

1st cost

8×$2000
=$16000
2nd cost
12×$2200
=$26400
The cost of the mixture per kg
=$16000+$26400/8+12
=$42400/20
=$2120

I know that the cost of coffee has gone up, but

$2000 per kg ????
I will assume that you meant $22.00, (even that is too high)

anyway.....

let the cost of the mix be $x per kg

8(20) + 12(22) = x(8+12)
20x = 424
x = $21.20

Thank you very much

To find the cost of the mixture per kg, we need to determine the total cost of the mixture and then divide it by the total weight of the mixture.

To calculate the total cost of the mixture:
1. Multiply the amount (weight) of the first kind of coffee (8 kg) by its cost per kg ($2000/kg). The result is 8 kg * $2000/kg = $16000.
2. Multiply the amount (weight) of the second kind of coffee (12 kg) by its cost per kg ($2200/kg). The result is 12 kg * $2200/kg = $26400.
3. Add the two results together: $16000 + $26400 = $42400.

To calculate the total weight of the mixture:
1. Add the weight of the first kind of coffee (8 kg) to the weight of the second kind of coffee (12 kg). The result is 8 kg + 12 kg = 20 kg.

To find the cost of the mixture per kg:
1. Divide the total cost of the mixture ($42400) by the total weight of the mixture (20 kg): $42400 / 20 kg = $2120/kg.

Therefore, the cost of the mixture per kg is $2120/kg.

I need your help about our mook paper i whant a answer

Well, let's do some coffee calculations! If you mix 8kg of coffee costing $2000 a kg with 12kg of coffee costing $2200, the total cost of the mixture would be... a lot of money. But fear not, I have my trusty calculator here.

The total cost of the first batch of coffee would be 8kg multiplied by $2000, which equals $16,000. The total cost of the second batch of coffee would be 12kg multiplied by $2200, which equals $26,400.

Now, to find the total cost of the mixture, we just need to add those two amounts together: $16,000 + $26,400 = $42,400.

To find the cost per kg of the mixture, we divide the total cost ($42,400) by the total weight of the mixture (8kg + 12kg = 20kg).

So, $42,400 ÷ 20kg = $2120 per kg.

Phew, that's one expensive cup of coffee!
