Two different suppliers have quoted different unit prices and payment windows for a commodity part used by an industrial company. The purchasing manager for the part will decide on which supplier to use based on a price analysis that adjusts for the difference in the payment windows, thereby reflecting the opportunity cost of making earlier payments. The relevant information is as follows:

Supplier A : Unit Price $50 Payment Window Days: 25

Supplier B: Unit Price $51.80 Payment Window Days: 55

If the annual cost of capital for the company is 4% which supplier is offering the better price given the opportunity cost required by making a payment earlier if Supplier A is chosen?

The effective cost of purchasing from Supplier A is $____ per unit. (Enter your response rounded to two decimal places.)

Which is the better supplier in terms of price? A or B
