Producing copies of a book costs m dollars for the first one thousand copies, n dollars for the next five hundred copies, and $2,65 for each copy thereafter. If C in dollars represents the total cost of producing R >1500 copies of the book, which equation is equivalent to C?

a.	C = (m + n)(2.65) + R
b.	C = (m + n)(R –1500)(2.65)
c.	C = (m + n) + (R –1500)(2.65)
d.	C = (R – m – n) + R(2.65)
e.	C = (m + n) + R(2.65)
