The owner of a shop wants to mix cashews and pecans to make 8 kg of mixed nuts worth $7.25 per kg. if the price of cashews is $8.00 per kg and the price of pecans is $7.00 per kg, how many kilograms of each should he take?

We solve as follows:

let x = amount cashews
    y = pecans

We have two unknowns. Therefore, we need to set up two equations. We do as follows:

8 = x + y
8(7.25) = 58 = 8x + 7y

x = 2 kg cashews
y = 6 kg pecans

Hope this answers the question. Have a nice day.
