I have an exam in two days. I need an explanation to this question please.
MC = 10+5Q
derive an equation for total cost

Integrate the MC function. MC is the first derivitive of TC. So,
TC = 10Q + (5/2)Q^2 + C 
A television station is considering the sale of promotional DVDs. It can have the DVDs produced by one of two suppliers. Supplier A will charge the station a setup fee of $1200 plus $2 for each DVD; supplier B has no setup fee and will charge $4 per DVD. The station estimates its demand for the DVDs to be given by Q = 1,600  200P, where P is the price in dollars and Q is the number of DVDs. The price equation is P = 8 Q/200
