Answer:
Mo's orchard
Step-by-step explanation:
To find who's orchard had more yield per tree, we simply divide the total number of harvest they got to the number of trees they have.
Jack's Yield
450 lb / 6 = 75 lb per tree
Mo's Yield
1215 / 15 = 81 lb per tree
So in conclusion, Mo's orchard had more yield per tree.
