A mailorder company charges $12 for each shirt. Shipping costs $f per oder.
Write a variable expression for the cost of odering x number of shirts

Suppose you buy x shirts to be shipped as one order. What is the cost of the shirts? What is the cost of shipping?

I think you need to know how many shirts were ordered per order. If ten shirts were ordered on ONE order, the cost is 10x+4
If ten shirts were ordered on ten orders, then cost is
10x+40
So I am not certain there is a definite answer here. 
sorry I wrote the questionwrong!!!

Write a variable expression for the cost of ordering x numbers of shirts. 
cost=12x+5
That is to order x shirts one one order.
