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 Corrected for 6 supp. --thanks, Steve! by Ady TZIDON)

If the total weight is 60 oz, then F is the cheater,
