Equation is 0.05*x*(x/y)
I have 3 sets of numbers (12, 5), (14, 6), and (25,10). These numbers are represented by (x,y) in the above equation.
Option 1: [0.05*12*(12/5)] + [0.05*14*(14/6)] + 0.05*25*(25/10)] = 6.198
Option 2: 0.05*(12+14+25)*[(12+14+25)/(5+6+10)] = 6.193
Why is there a difference in the result? Is there a term that explains this?
