Answer:
There would be 12 total picks.
Step-by-step explanation:
In order to find this, create a proportional equality in which the top of the equation is the number of orange picks and the bottom is the number of green picks.
2/1 = x/4
Now we cross multiply to find out the total number of picks.
1*x = 4*2
x = 8
Now that we have the number of orange picks, we add to the number of green picks for the total number.
4 + 8 = 12
