Bristol is developing material standards for her company. The operations manager wants grade A plastic tops because they are the easiest to work with and are the quality the customers want. Grade B will not work because customers do not want the lower grade, and it takes more time to assemble the product than with grade A materials. Bristol calls several suppliers to get prices for the plastic top. All are within $0.10 of each other. Since the company will use millions of the plastic tops, she decides that the $0.10 difference is important. The supplier who has the lowest price is known for delivering late and low-quality materials. Bristol decides to use the supplier who is $0.04 more but delivers on time and at the right quality. This supplier charges $0.52 per plastic top. Each unit of product requires six plastic tops. What is the standard cost per unit for plastic tops?
