A publisher prints copies of a popular weekly tabloid for distribution and sale. The fixed costs are $500 per print run, with each copy printed costing an additional $0.40. If C(q) is the cost function (in \$) of the price of the print run as a function of copies printed, what is the formula for C(q) ? C(q)=500+0.4q C(q)=500q+0.4 C(q)=(500+0.4)q C(q)=5000.4q C(q)=500q0.4
