I need help doing the math.

You will build a simulation of a population using the same elements as the simulation pictured here and show how the traits in this population change in years 5 and 10.

several red, blue, and green circles representing different traits in a population, with one circle being equivalent to 50 organisms

Start off with 2,500 plants of which 50% have medium-tip leaves, 25% have wide-tip leaves, and 25% have drip-tip leaves. Each circle in your simulation will represent 125 organisms. Calculate how many circles you need for each trait, and then create your simulation.
