The function c(p) represents the total cost for a factory to produce p parts. c(p)=12.5p+4500 what does the value 4500 represent in this situation?

The function works as follows:

If, for example, we want to produce 100 parts, the total cost is calculated as follows:

c(100)=12.5*100+4,500=1,250+4,500=5,750 (dollars, or some other unit). 

We note that if p=0 (that is, if no parts are produced) then
                               p(0)=12.5*0+4,500=0+4,500=4,500. 

Thus, 4,500 represents the initial costs, without producing any part.

221,500 is the answer
