A grocer has six suppliers with each supplier selling a different brand of tea in 4-ounce packets at $ 20 per packet. The grocer knows that one of the suppliers gives short weight, each packet of his brand weighing only 3.75 ounces.

Using a digital scale with only one weighing, what is the minimum amount the grocer must spend to be sure of finding the supplier who gives short weight?

(In reply to re: Corrected for 6 supp. --thanks, Steve! by Steve Herman)

Thanks again.
