Question

Pecans that cost 28.50 per kilogram were mixed with almonds that cost 22.25 per kilogram. How many kilograms of each were used to make a 25 kilogram mixture costing 24.25 per kilogram

Answer 1

8 kilograms=pecans

17 kilograms=almonds

Explanation:

Set up this graph as seen in the attachment. Multiply across and get your answers under the “I” column. Do the first box + second box=3rd box (top to bottom under interest.) solve for x. Once you get 8 kg, you will plug 8 into each of the two boxes under “P”, one of them being x and the other being 25-x. This is how you get 8 kg pecans and 17 kg almonds.
