Calculus Word Problem?

So the answer to the question is $960 
I just want to know the steps to get the answer. 

A fence must be built in a large field to enclose a rectangular area of 25600 m^2. 
One side of the area is bounded by an existing fence; no fence is needed there. Material for the fence cost $3 per meter for the two ends, and $1.50 per meter for the side opposite the existing fence. Find the cost of the least expensive fence. 

It's on optimization if that matters.
