Calculate the number 2394

A woman goes into Wal-Mart to buy a rod and reel. She doesn't know which one to get so she just grabs one and goes over to the register. There is a Wal-Mart "associate" standing there with dark shades on. She says, "Excuse me sir...can you tell me anything about this rod and reel?" He says, "Ma'am I'm blind but if you will drop it on the counter I can tell you everything you need to know about it from the sound that it makes." She didn't believe him, but dropped it on the counter anyway. He said, "That's a 6' graphite rod with a Zebco 202 reel and 10 lb. test line...It's a good all around rod and reel and it's $20.00". She says, "Thats amazing that you can tell all that just by the sound Of it dropping on the counter. I think it's what I'm looking for so I'll take it." He walks behind the counter to the register, and in the meantime the woman farts. At first she is embarrassed but then realizes that there is no way he could tell it was her..being blind he wouldn't know that she was the only person around. He rings up the sale and says, "That will be $25.50." She says, "But didn't you say it was $20.00?" He says, "Yes ma'am, the rod and reel is $20.00, the duck call is $3.00, and the stink bait is$2.50."
