Answer:
R=10x
C=2x+7000
P=R-C
a)
Substitute R and C into the equation for P:
P=10x - (2x+7000)
Now substitute 1000 for x and solve for P which is the company's profit if they sell 1000 pens.
b)
Set R equal to C
R=C
Plug in R=10x and C=2x+7000
10x=2x+7000
Solve for x which will be the amount of pens required to be sold to break even.
