Let
x------> parts produced by the first team <span>according to the plan
</span>y------> parts produced by the second team according to the plan
we know that
x+y=680--------> equation 1
0.20x+0.15y=118--------> equation 2
using a graph tool
see the attached figure
the solution is
x=320
y=360
the answer isparts produced by the first team according to the plan------> 320parts produced by the second team according to the plan----> 360
