View Full Version : word problem: yearly reorder cost

I am lost with this problem. Do I get "x" by itself? I'm confused.

Suppose a store orders 3,000 items each year. If it orders x units at a time, the number N of reorders is N = 3000/x

If there is a fixed $20 reorder fee and a $3 charge per item, the cost of each order
is C = 20 + 3x

The yearly reorder cost CR is then given by CR = (N)(C)

What is the yearly reorder cost?

Multiply the expression for N by the expression for C. Simplify to get CR.
