  Circumference(in): Height(ft): Crown Spread (ft): Total Points
Angel Oak:   306:   65:   144: 407
Green Ash:   181: 143: 96: 348
Redwood: 168: 105: 44:   284

Let circumference be x ; height be y ; crown spread be z.
306x + 65y + 144z = 407
181x + 143y + 96z = 348
168x + 105y +44z = 248

Choices:
a. circumference: 1 point; height: 1 point; crown spread: 0.75 point
b. circumference: 2 point;s height: 1 point; crown spread: 0.25 point
c. circumference: 1 point; height: 2 points; crown spread: 0.25 point
d. circumference: 1 point; height: 1 point; crown spread: 0.25 point

Answer would be Choice D.
306(1) + 65(1) + 144(0.25) = 407
181(1) + 143(1) + 96(0.25) = 348
168(1) + 105(1) +44(0.25) = 248
