Construct a triangle out of the points then find the midpoint of each side
Multiply with 25
25*5 quarts +25*1 pints +25*6 oz
125 quarts +25 pints +150 oz
So it would be $8.65/ 5lbs. And divide the top and the bottom by 5 and you get $1.73/ 1 lbs. I hope this helps!
I tried but I hope this helps. If you’re confused please feel free to ask
