Question 65818: I asked this problem already and received an answer, but my teacher has said I need to have a certain format for the answer. I have looked and looked but to no help do not understand what she is looking for, thank you for the help:
The demand equation for a certain type of printer is given by:
D = -200p + 35,000
The supply equation is predicted to be:
S = -p^2 + 400p - 20,000
The answer I recieved was:
P = 487.08 and P = 112.92
Can anyone help me figure out what I am to use for a format and how it is to be set up. Thank you.
