An order for bottles of juice costs $12.04 per bottle plus a shipping charge of $4.80 regardless of the number of bottles ordered. Over the past year, 100 orders for bottles of juice have been received. The standard deviation of the numbers of bottles per order for the 100 orders is 1.5 bottles. What is the standard deviation of the 100 costs for the orders?

I am not sure if this is a GRE problem but the standard deviation of the costs are given by 12.04*1.5=18.06
